These objects get constructed semi-frequently (any time a parser is
deserialized) and so info logs are spammy. They'll still appear in
task logs at least once, since they're part of the task definition and
will get logged due to that.

* Ignore chunkPeriod for groupBy v2, fix chunkPeriod for irregular periods.
Includes two fixes:
- groupBy v2 now ignores chunkPeriod, since it wouldn't have helped anyway (its mergeResults
returns a lazy sequence) and it generates incorrect results.
- Fix chunkPeriod handling for periods of irregular length, like "P1M" or "P1Y".
Also includes doc and test fixes:
- groupBy v1 was no longer being tested by GroupByQueryRunnerTest since #3953, now it
is once again.
- chunkPeriod documentation was misleading due to its checkered past. Updated it to
be more accurate.

- Added support for time zones other than UTC via a "timeZone" context.

Also some bug fixes:

* SQL: Add resolution parameter to quantile agg, rename to APPROX_QUANTILE.
* Fix bug with re-use of filtered approximate histogram aggregators.
Also add APPROX_QUANTILE tests for filtering and running on complex columns.
Includes some slight refactoring to allow tests to make DruidTables that
include complex columns.
* Remove unused import
* SQL: Ditch CalciteConnection layer and add DruidMeta, extension aggregators.
Switched from CalciteConnection to Planner, bringing benefits:
- CalciteConnection's JDBC interface no longer sits between the SQL server
(HTTP/Avatica) and Druid's query layer. Instead, the SQL servers can use
Druid Sequence objects directly, reducing overhead in the query return path.
- Implemented our own Planner-based Avatica Meta, letting us control
connection timeouts and connection / statement limits. The previous
CalciteConnection-based implementation didn't have any limits or timeouts.
- The Planner interface lets us override the operator table, opening up
SQL language extensions. This patch includes two: APPROX_COUNT_DISTINCT
in core, and a QUANTILE aggregator in the druid-histogram extension.
Also:
- Added INFORMATION_SCHEMA metadata schema.
- Added tests for Unicode literals and escapes.
* Verify statement is actually open before closing it.

* Reduce visibility of NamespaceExtractionCacheManager.cacheCount() and monitor() implementations, and don't run NamespaceExtractionCacheManagerExecutorsTest with off-heap cache (it didn't before)
* In NamespaceLookupExtractorFactory, use safer idiom to check if CacheState is NoCache or VersionedCache
* More logging in CacheHandler constructor and close(), VersionedCache.close()
* PR comments addressed
* Make CacheScheduler.EntryImpl AutoCloseable, avoid 'dispose' verb in comments, logging and naming in CacheScheduler in favor of 'close'
* More Javadoc comments to CacheScheduler
* Fix NPE
* Remove logging in OnHeapNamespaceExtractionCacheManager.expungeCollectedCaches()
* Make NamespaceExtractionCacheManagersTest.testRacyCreation() to have similar load to what it be before the refactoring

* More comments on MapDbCacheDisposer.disposed
* Replace concat with Long.toString()
* Comment on why NamespaceExtractionCacheManager.scheduledExecutorService() returns ScheduledThreadPoolExecutor
* Place logging statements in VersionedCache.close() and CacheHandler.close() after actual closing logic, because logging may fail

* Don't close the whole CacheScheduler.Entry, if the cache update task failed
* Replace AtomicLong updateCounter and firstRunLatch with Phaser-based UpdateCounter in CacheScheduler.EntryImpl
* Fix#3795 (Java 7 compatibility).

if the next offset is less than the earliest available offset for that partition
* review comments

This also involved some other test changes:
- Added a factory.mergeRunners step to AggregationTestHelper's groupBy chain, since the v2
engine does merging there.
- Changed test byteBuffer pools from on-heap to off-heap to work around
https://github.com/DataSketches/sketches-core/pull/116 for datasketches tests.
Excludes tests from AvoidStaticImport, since those are used often there and
I didn't want to make this changeset too large. Production code use was minimal
and I switched those to non-static imports.
* Rename ExtractionNamespaceCacheFactory.getCachePopulator() to populateCache() and make it to populate cache itself instead of returning a Callable which populates cache, because this "callback style" is not actually needed.
ExtractionNamespaceCacheFactory isn't a "factory" so it should be renamed, but renaming right in this commit would tear the git history for files, because ExtractionNamespaceCacheFactory implementations have too many changed lines. Going to rename ExtractionNamespaceCacheFactory to something like "CachePopulator" in one of subsequent PRs.
This commit is a part of a bigger refactoring of the lookup cache subsystem.
* Remove unused line and imports
* URIExtractionNamespace: Treat null values in lookup maps as missing entries.
This is useful when many logical lookups are derived from the same base JSON file,
and some lookups' values may be unknown sometimes.
* Add test, logging message, and address other comments.
* Update docs.
* Return better lastVersion from JDBCExtractionNamespaceCacheFactory's cache populator callable
* Return the lastVersion if URI lookup last modified date is not later than the last cached, from URIExtractionNamespaceCacheFactory's cache populator callable
* Fix a race condition in NamespaceExtractionCacheManager.cancelFuture()
* Don't delete cache from NamespaceExtractionCacheManager if the ExtractionNamespaceCacheFactory returned the same version as the last; Better exception treatment in the scheduled cache updater runnable in NamespaceExtractionCacheManager (in particular, don't consume Errors); throw AssertionError in StaticMapExtractionNamespaceCacheFactory if the lastVersion != null)
* In NamespaceExtractionCacheManager, put NamespaceImplData.latestVersion update in the same synchronized() block with swapAndClearCache(id, cacheId); Turn getPostRunnable which returns a callback into a simple updateNamespace() method
* In StaticMapExtractionNamespaceCacheFactory.getCachePopulator(), check the input directly, not inside a callback
* In URIExtractionNamespaceCacheFactory, allow URI last modified time to go backwards
* Better logging in NamespaceExtractionCacheManager
* Add comment on lastVersion nullability in URIExtractionNamespaceCacheFactory
