### What changes were proposed in this pull request?
This PR upgrades Kubernetes and Minikube version for integration tests and removes/updates the old code for this new version.
Details of this changes:
- As [discussed in the mailing list](http://apache-spark-developers-list.1001551.n3.nabble.com/minikube-and-kubernetes-cluster-versions-for-integration-testing-td30856.html): updating Minikube version from v0.34.1 to v1.7.3 and kubernetes version from v1.15.12 to v1.17.3.
- making Minikube version checked and fail with an explanation when the test is started with on a version < v1.7.3.
- removing minikube status checking code related to old Minikube versions
- in the Minikube backend using fabric8's `Config.autoConfigure()` method to configure the kubernetes client to use the `minikube` k8s context (like it was in [one of the Minikube's example](https://github.com/fabric8io/kubernetes-client/blob/master/kubernetes-examples/src/main/java/io/fabric8/kubernetes/examples/kubectl/equivalents/ConfigUseContext.java#L36))
- Introducing `persistentVolume` test tag: this would be a temporary change to skip PVC tests in the Kubernetes integration test, as currently the PCV tests are blocking the move to Docker as Minikube's driver (for details please check https://issues.apache.org/jira/browse/SPARK-34738).
### Why are the changes needed?
With the current suggestion one can run into several problems without noticing the Minikube/kubernetes version is the problem.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
It was tested on Mac with [this script](https://gist.github.com/attilapiros/cd58a16bdde833c80c5803c337fffa94#file-check_minikube_versions-zsh) which installs each Minikube versions from v1.7.2 (including this version to test the negative case of the version check) and runs the integration tests.
It was started with:
```
./check_minikube_versions.zsh > test_log 2>&1
```
And there was only one build failure the rest was successful:
```
$ grep "BUILD SUCCESS" test_log | wc -l
26
$ grep "BUILD FAILURE" test_log | wc -l
1
```
It was for Minikube v1.7.2 and the log is:
```
KubernetesSuite:

### What changes were proposed in this pull request?
From [minikube version v1.1.0](https://github.com/kubernetes/minikube/blob/v1.1.0/CHANGELOG.md) kubectl is available as a command. So the kubeconfig settings can be accessed like:
```
$ minikube kubectl config view
apiVersion: v1
clusters:
- cluster:
certificate-authority: /Users/attilazsoltpiros/.minikube/ca.crt
server: https://127.0.0.1:32788
name: minikube
contexts:
- context:
cluster: minikube
namespace: default
user: minikube
name: minikube
current-context: minikube
kind: Config
preferences: {}
users:
- name: minikube
user:
client-certificate: /Users/attilazsoltpiros/.minikube/profiles/minikube/client.crt
client-key: /Users/attilazsoltpiros/.minikube/profiles/minikube/client.key
```
Here the vm-driver was docker and the server port (https://127.0.0.1:32788) is different from the hardcoded 8443.
So the main part of this PR is introducing kubernetes client configuration based on the kubeconfig (output of `minikube kubectl config view`) in case of minikube versions after v1.1.0 and the old legacy way of configuration is also kept as minikube version should be supported back to v0.34.1 .
Moreover as the old style of config parsing pattern wasn't sufficient in my case as when the `minikube kubectl config view` is called kubectl downloading message might be included before the first key I changed it even for the existent keys to be a consistent pattern in this file.
The old parsing in an example:
```
private val HOST_PREFIX = "host:"
val hostString = statusString.find(_.contains(s"$HOST_PREFIX "))
val status1 = hostString.get.split(HOST_PREFIX)(1)
```
The new parsing:
```
private val HOST_PREFIX = "host: "
val hostString = statusString.find(_.contains(HOST_PREFIX))
hostString.get.split(HOST_PREFIX)(1)
```
So the PREFIX is extended with the extra space at the declaration (this way the two separate string operation are more safe and consistent with each other) and the replace is changed to split and getting the 2nd string from the result (which is guaranteed to contain only the text after the PREFIX when the PREFIX is a contained substring).
Finally there is tiny change in `dev-run-integration-tests.sh` to introduce `--skip-building-dependencies` which switchs off building of maven dependencies of `kubernetes-integration-tests` from the Spark project.
This could be used when only the `kubernetes-integration-tests` should be rebuilded as only the tests are modified.
### Why are the changes needed?
Kubernetes client configuration based on kubeconfig settings is more reliable and provides a solution which is minikube version independent.
### Does this PR introduce _any_ user-facing change?
No. This is only test code.
### How was this patch tested?
tested manually on two minikube versions.

Signed-off-by: Dongjoon Hyun <dongjoon@apache.org>
This PR is based on an existing/previou PR - https://github.com/apache/spark/pull/19045
### What changes were proposed in this pull request?
This changes adds a decommissioning state that we can enter when the cloud provider/scheduler lets us know we aren't going to be removed immediately but instead will be removed soon. This concept fits nicely in K8s and also with spot-instances on AWS / preemptible instances all of which we can get a notice that our host is going away. For now we simply stop scheduling jobs, in the future we could perform some kind of migration of data during scale-down, or at least stop accepting new blocks to cache.
There is a design document at https://docs.google.com/document/d/1xVO1b6KAwdUhjEJBolVPl9C6sLj7oOveErwDSYdT-pE/edit?usp=sharing
### Why are the changes needed?
With more move to preemptible multi-tenancy, serverless environments, and spot-instances better handling of node scale down is required.
### Does this PR introduce any user-facing change?
There is no API change, however an additional configuration flag is added to enable/disable this behaviour.
### How was this patch tested?
New integration tests in the Spark K8s integration testing. Extension of the AppClientSuite to test decommissioning seperate from the K8s.

### What changes were proposed in this pull request?
This PR aims to support JDK11 test in K8S integration tests.
- This is an update in testing framework instead of individual tests.
- This will enable JDK11 runtime test when you didn't installed JDK11 on your local system.
### Why are the changes needed?
Apache Spark 3.0.0 adds JDK11 support, but K8s integration tests use JDK8 until now.
### Does this PR introduce any user-facing change?
No. This is a dev-only test-related PR.
### How was this patch tested?
This is irrelevant to Jenkins UT, but Jenkins K8S IT (JDK8) should pass.
- https://github.com/apache/spark/pull/27559#issuecomment-585903489 (JDK8 Passed)
And, manually do the following for JDK11 test.

## What changes were proposed in this pull request?
As discovered by users making use of this feature, there is a bug in the
declaration of the `R_IMAGE_NAME` variable that causes the default name to
not be properly set to `spark-r` but rather to just `-r`
## How was this patch tested?
Verified that the image name for the R image is now appropriately populated in the integration test script via Bash debug output.
NB - The fact that this wasn't spotted earlier highlights the fact that currently the K8S integration test suite does not have any tests for the R image as if it had this would have failed integration testing in the original PR #23846Closes#24449 from rvesse/SPARK-26729.

## What changes were proposed in this pull request?
Allow specifying system properties to customise the image names for the images used in the integration testing. Useful if your CI/CD pipeline or policy requires using a different naming format.
This is one part of addressing SPARK-26729, I plan to have a follow up patch that will also make the names configurable when using `docker-image-tool.sh`
## How was this patch tested?
Ran integration tests against custom images generated by our CI/CD pipeline that do not follow Spark's existing hardcoded naming conventions using the new system properties to override the image names appropriately:

## What changes were proposed in this pull request?
Currently K8S integration tests are hardcoded to use a `minikube` based backend. `minikube` is VM based so can be resource hungry and also doesn't cope well with certain networking setups (for example using Cisco AnyConnect software VPN `minikube` is unusable as it detects its own IP incorrectly).
This PR Adds a new K8S integration testing backend that allows for using the Kubernetes support in [Docker for Desktop](https://blog.docker.com/2018/07/kubernetes-is-now-available-in-docker-desktop-stable-channel/). It also generalises the framework to be able to run the integration tests against an arbitrary Kubernetes cluster.
To Do:
- [x] General Kubernetes cluster backend
- [x] Documentation on Kubernetes integration testing
- [x] Testing of general K8S backend
- [x] Check whether change from timestamps being `Time` to `String` in Fabric 8 upgrade needs additional fix up

* Move the files from the repo root into resource-managers/kubernetes/integration-tests
* Add a reference to these tests in the root README.md
* Fix a path reference in dev/dev-run-integration-tests.sh
* Add a TODO in include/util.sh
