[SPARK-11647][WIP] Attempt to reduce time/flakiness of Thriftserver CLI and
SparkSubmit tests
This work-in-progress patch aims to reduce the test time and flakiness of
HiveSparkSubmitSuite, SparkSubmitSuite, and CliSuite.
Key changes:
- Disable IO synchronization calls for Derby writes, since durability
doesn't matter for tests. This was done for HiveCompatibilitySuite in #6651 and
resulted in huge test speedups.
- Add a few missing `--conf`s to disable various Spark UIs. The CliSuite,
in particular, never disabled these UIs, leaving it prone to
port-contention-related flakiness.
- Fix two instances where tests defined `beforeAll()` methods which were
never called because the appropriate traits were not mixed in. I updated these
tests suites to extend `BeforeAndAfterEach` so that they play nicely with our
`ResetSystemProperties` trait.
