Add dynamic coordinator config that allows control over how many segments are considered when picking a segment to move. (#10284)
* dynamic coord config adding more balancing control

add new dynamic coordinator config, maxSegmentsToConsiderPerMove. This
config caps the number of segments that are iterated over when selecting
a segment to move. The default value combined with current balancing
strategies will still iterate over all provided segments. However,
setting this value to something > 0 will cap the number of segments
visited. This could make sense in cases where a cluster has a very large
number of segments and the admins prefer less iterations vs a thorough
consideration of all segments provided.

Fixes and tests related to the Indexer process. (#10631)
* Fixes and tests related to the Indexer process.

Three bugs fixed:

1) Indexers would not announce themselves as segment servers if they
   did not have storage locations defined. This used to work, but was
   broken in #9971. Fixed this by adding an "isSegmentServer" method
   to ServerType and updating SegmentLoadDropHandler to always announce
   if this method returns true.

2) Certain batch task types were written in a way that assumed "isReady"
   would be called before "run", which is not guaranteed. In particular,
   they relied on it in order to initialize "taskLockHelper". Fixed this
   by updating AbstractBatchIndexTask to ensure "isReady" is called
   before "run" for these tasks.

3) UnifiedIndexerAppenderatorsManager did not properly handle complex
   datasources. Introduced DataSourceAnalysis in order to fix this.

Test changes:

1) Add a new "docker-compose.cli-indexer.yml" config that spins up an
   Indexer instead of a MiddleManager.

2) Introduce a "USE_INDEXER" environment variable that determines if
   docker-compose will start up an Indexer or a MiddleManager.

3) Duplicate all the jdk8 tests and run them in both MiddleManager and
   Indexer mode.

4) Various adjustments to encourage fail-fast errors in the Docker
   build scripts.

5) Various adjustments to speed up integration tests and reduce memory
   usage.

6) Add another Mac-specific approach to determining a machine's own IP.
   This was useful on my development machine.

7) Update segment-count check in ITCompactionTaskTest to eliminate a
   race condition (it was looking for 6 segments, which only exist
   together briefly, until the older 4 are marked unused).

Javadoc updates:

1) AbstractBatchIndexTask: Added javadocs to determineLockGranularityXXX
   that make it clear when taskLockHelper will be initialized as a side
   effect. (Related to the second bug above.)

2) Task: Clarified that "isReady" is not guaranteed to be called before
   "run". It was already implied, but now it's explicit.

3) ZkCoordinator: Clarified deprecation message.

4) DataSegmentServerAnnouncer: Clarified deprecation message.
