### What changes were proposed in this pull request?
This PR proposes to exclude `org.apache.hadoop:hadoop-yarn-server-resourcemanager:jar:tests` from `hadoop-yarn-server-tests` when we use Hadoop 2 profile.
For some reasons, after SBT 1.3 upgrade at SPARK-21708, SBT starts to pull the dependencies of 'hadoop-yarn-server-tests' with 'tests' classifier:
```
org/apache/hadoop/hadoop-common/2.7.4/hadoop-common-2.7.4-tests.jar
org/apache/hadoop/hadoop-yarn-common/2.7.4/hadoop-yarn-common-2.7.4-tests.jar
org/apache/hadoop/hadoop-yarn-server-resourcemanager/2.7.4/hadoop-yarn-server-resourcemanager-2.7.4-tests.jar
```
these were not pulled before the upgrade.
This specific `hadoop-yarn-server-resourcemanager-2.7.4-tests.jar` causes the problem (SPARK-33104)
1. When the test case creates the Hadoop configuration here,
cc06266ade/core/src/main/scala/org/apache/spark/deploy/SparkHadoopUtil.scala (L122)
2. Such jars above have higher precedence in the class path, instead of the specified custom `core-site.xml` in the test:
e93b8f02cd/resource-managers/yarn/src/main/scala/org/apache/spark/deploy/yarn/Client.scala (L1375)
3. Later, `core-site.xml` in the jar is picked instead in Hadoop's `Configuration`:
Before this fix:
```
jar:file:/.../https/maven-central.storage-download.googleapis.com/maven2/org/apache/hadoop/
hadoop-yarn-server-resourcemanager/2.7.4/hadoop-yarn-server-resourcemanager-2.7.4-tests.jar!/core-site.xml
```
After this fix:
```
file:/.../spark/resource-managers/yarn/target/org.apache.spark.deploy.yarn.YarnClusterSuite/
org.apache.spark.deploy.yarn.YarnClusterSuite-localDir-nm-0_0/
usercache/.../filecache/10/__spark_conf__.zip/__hadoop_conf__/core-site.xml
```
4. the `core-site.xml` in the jar of course does not contain:
2cfd215dc4/resource-managers/yarn/src/test/scala/org/apache/spark/deploy/yarn/YarnClusterSuite.scala (L133-L141)
and the specific test fails.
This PR uses some kind of hacky approach. It was excluded from 'hadoop-yarn-server-tests' with 'tests' classifier, and then added back as a proper dependency (when Hadoop 2 profile is used). In this way, SBT does not pull `hadoop-yarn-server-resourcemanager` with `tests` classifier anymore.
### Why are the changes needed?
To make the build pass. This is a blocker.
### Does this PR introduce _any_ user-facing change?
No, test-only.
### How was this patch tested?
Manually tested and debugged:
```bash
build/sbt clean "yarn/testOnly *.YarnClusterSuite -- -z SparkHadoopUtil" -Pyarn -Phadoop-2.7 -Phive -Phive-2.3
```
