Avoid `UnsupportedOperationException` from JsonRDD.inferSchema on empty RDD.
Not sure if this is supposed to be an error (but a better one), but it seems like this case can come up if the input is down-sampled so much that nothing is sampled.

```
sqlContext.jsonRDD(sc.parallelize(List[String]()))

just results in

This change encapsulates all the logic involved in launching a Spark job
into a small Java library that can be easily embedded into other applications.
The overall goal of this change is twofold, as described in the bug:
- Provide a public API for launching Spark processes. This is a common request
from users and currently there's no good answer for it.
- Remove a lot of the duplicated code and other coupling that exists in the
different parts of Spark that deal with launching processes.
A lot of the duplication was due to different code needed to build an
application's classpath (and the bootstrapper needed to run the driver in
certain situations), and also different code needed to parse spark-submit
command line options in different contexts. The change centralizes those
as much as possible so that all code paths can rely on the library for
handling those appropriately.

Right now we have a method to specifically download boto. This PR generalizes it so it's easy to download additional libraries if we want.
For example, adding new external libraries for spark-ec2 is now as simple as:
```python
external_libs = [
{
"name": "boto",
"version": "2.34.0",
"md5": "5556223d2d0cc4d06dd4829e671dcecd"
},
{
"name": "PyYAML",
"version": "3.11",
"md5": "f50e08ef0fe55178479d3a618efe21db"
},
{
"name": "argparse",
"version": "1.3.0",
"md5": "9bcf7f612190885c8c85e30ba41db3c7"
}
]
```
Likely use cases:
* Downloading PyYAML to allow spark-ec2 configs to be persisted as a YAML file. ([SPARK-925](https://issues.apache.org/jira/browse/SPARK-925))
* Downloading argparse to clean up / modernize our option parsing.
First run output, with PyYAML and argparse added just for demonstration purposes:
```shell
$ ./spark-ec2 --version
Downloading external libraries that spark-ec2 needs from PyPI to /path/to/spark/ec2/lib...
This should be a one-time operation.
- Downloading boto...
- Finished downloading boto.
- Downloading PyYAML...
- Finished downloading PyYAML.
- Downloading argparse...
- Finished downloading argparse.
spark-ec2 1.2.1
```
Output thereafter:
```shell

spark-ec2 1.2.1
```

Because circular reference between JavaObject and JavaMember, an Java object can not be released until Python GC kick in, then it will cause memory leak in collect(), which may consume lots of memory in JVM.

As described in https://issues.apache.org/jira/browse/SPARK-6188 and discovered in https://issues.apache.org/jira/browse/SPARK-5838.
When re-starting a cluster, if the user does not provide the instance types, which is the recommended behavior in the docs currently, the instance will be assigned the default type m1.large. This then affects the setup of the machines.
This solves this by getting the instance types from the existing instances, and overwriting the default options.
EDIT: Further clarification of the issue:
In short, while the instances themselves are the same as launched, their setup is done assuming the default instance type, m1.large.
This means that the machines are assumed to have 2 disks, and that leads to problems that are described in in issue [5838](https://issues.apache.org/jira/browse/SPARK-5838), where machines that have one disk end up having shuffle spills in the in the small (8GB) snapshot partitions that quickly fills up and results in failing jobs due to "No space left on device" errors.
Other instance specific settings that are set in the spark_ec2.py script are likely to be wrong as well.

When looking for a cluster, spark-ec2 currently pulls down [info for all instances](eb48fd6e9d/ec2/spark_ec2.py (L620)) and filters locally. When working on an AWS account with hundreds of active instances, this step alone can take over 10 seconds.
This PR improves how spark-ec2 searches for clusters by pushing the filter up to EC2.
Basically, the problem (and solution) look like this:
```python
>>> timeit.timeit('blah = conn.get_all_reservations()', setup='from __main__ import conn', number=10)
116.96390509605408
>>> timeit.timeit('blah = conn.get_all_reservations(filters={"instance.group-name": ["my-cluster-master"]})', setup='from __main__ import conn', number=10)
4.629754066467285
```
Translated to a user-visible action, this looks like (against an AWS account with ~200 active instances):
```shell
# master
$ python -m timeit -n 3 --setup 'import subprocess' 'subprocess.call("./spark-ec2 get-master my-cluster --region us-west-2", shell=True)'
...
3 loops, best of 3: 9.83 sec per loop
# this PR
$ python -m timeit -n 3 --setup 'import subprocess' 'subprocess.call("./spark-ec2 get-master my-cluster --region us-west-2", shell=True)'
...
3 loops, best of 3: 1.47 sec per loop
```
This PR also refactors `get_existing_cluster()` to make it, I hope, simpler.
Finally, this PR fixes some minor grammar issues related to printing status to the user. 🎩👏

`LogicalPlan#resolve` will not only produce `Attribute`, but also "`GetField` chain".
So in `ResolveSortReferences`, after resolve the ordering expressions, we should not just collect the `Attribute` results, but also `Attribute` at the bottom of "`GetField` chain".

This patch fixes two issues with the executor log viewing links added in Spark 1.3. In standalone mode, the log URLs might include a port value of 0 rather than the actual bound port of the UI, which broke the ability to view logs from workers whose web UIs had been configured to bind to ephemeral ports. In addition, the URLs used workers' local hostnames instead of respecting SPARK_PUBLIC_DNS, which prevented this feature from working properly on Spark EC2 clusters because the links would point to internal DNS names instead of external ones.
I included tests for both of these bugs:
- We now browse to the URLs and verify that they point to the expected pages.
- To test SPARK_PUBLIC_DNS, I changed the code that reads the environment variable to do so via `SparkConf.getenv`, then used a custom SparkConf subclass to mock the environment variable (this pattern is used elsewhere in Spark's tests).

A simple wrapper around the Scala implementation. `DataFrame` is used for serialization/deserialization. Methods that return `RDD`s are not supported in this PR.
davies If we recognize Scala's `Product`s in Py4J, we can easily add wrappers for Scala methods that returns `RDD[(Double, Double)]`. Is it easy to register serializer for `Product` in PySpark?
