[SPARK-32245][INFRA] Run Spark tests in Github Actions

This PR aims to run the Spark tests in Github Actions.

To briefly explain the main idea:

- Reuse `dev/run-tests.py` with SBT build
- Reuse the modules in `dev/sparktestsupport/modules.py` to test each module
- Pass the modules to test into `dev/run-tests.py` directly via `TEST_ONLY_MODULES` environment variable. For example, `pyspark-sql,core,sql,hive`.
- `dev/run-tests.py` _does not_ take the dependent modules into account but solely the specified modules to test.

Another thing to note might be `SlowHiveTest` annotation. Running the tests in Hive modules takes too much so the slow tests are extracted and it runs as a separate job. It was extracted from the actual elapsed time in Jenkins:

![Screen Shot 2020-07-09 at 7 48 13 PM](https://user-images.githubusercontent.com/6477701/87050238-f6098e80-c238-11ea-9c4a-ab505af61381.png)

So, Hive tests are separated into to jobs. One is slow test cases, and the other one is the other test cases.

_Note that_ the current GitHub Actions build virtually copies what the default PR builder on Jenkins does (without other profiles such as JDK 11, Hadoop 2, etc.). The only exception is Kinesis https://github.com/apache/spark/pull/29057/files#diff-04eb107ee163a50b61281ca08f4e4c7bR23

Last week and onwards, the Jenkins machines became very unstable for many reasons:
  - Apparently, the machines became extremely slow. Almost all tests can't pass.
  - One machine (worker 4) started to have the corrupt `.m2` which fails the build.
  - Documentation build fails time to time for an unknown reason in Jenkins machine specifically. This is disabled for now at apache#29017.
  - Almost all PRs are basically blocked by this instability currently.

The advantages of using Github Actions:
  - To avoid depending on few persons who can access to the cluster.
  - To reduce the elapsed time in the build - we could split the tests (e.g., SQL, ML, CORE), and run them in parallel so the total build time will significantly reduce.
  - To control the environment more flexibly.
  - Other contributors can test and propose to fix Github Actions configurations so we can distribute this build management cost.

Note that:
- The current build in Jenkins takes _more than 7 hours_. With Github actions it takes _less than 2 hours_
- We can now control the environments especially for Python easily.
- The test and build look more stable than the Jenkins'.

No, dev-only change.

Tested at #4

Closes apache#29057 from HyukjinKwon/migrate-to-github-actions.
