* MSQ: Validate that strings and string arrays are not mixed.
When multi-value strings and string arrays coexist in the same column,
it causes problems with "classic MVD" style queries such as:
select * from wikipedia -- fails at runtime
select count(*) from wikipedia where flags = 'B' -- fails at planning time
select flags, count(*) from wikipedia group by 1 -- fails at runtime
To avoid these problems, this patch adds type verification for INSERT
and REPLACE. It is targeted: the only type changes that are blocked are
string-to-array and array-to-string. There is also a way to exclude
certain columns from the type checks, if the user really knows what
they're doing.

* MSQ: Plan without implicit sorting.
This patch adds an EngineFeature "GROUPBY_IMPLICITLY_SORTS" and sets
it true for native, false for MSQ. It's useful for two reasons:
1) In the future we'll likely want MSQ to hash-partition for GROUP BY
instead of using a global sort, which would mean MSQ would not
implicitly ORDER BY when there is a GROUP BY.
2) When doing REPLACE with MSQ, CLUSTERED BY is transformed to ORDER BY.
We should retain that ORDER BY, as it may be a subset of the GROUP BY,
and it is important to remember which fields the user wanted to include in
range shard specs.
* Fix tests.
* Fix tests for real.
* Fix test.
ConcurrentGrouper kind of misuses ThreadLocal to hold a SpillingGrouper, and never calls remove() on it, which can result in large amounts of heap being retained as weak references even after grouping is finished. This PR calls keySerde.reset() on all of the Grouper.close() implementations that have a KeySerde and should free up a bunch of space that is no longer needed.
Changes
- Replace usages of `UnknownSegmentIdsException` with `DruidException`
- Add method `SqlMetadataQuery.retrieveSegments`
- Add new field `used` to `DataSegmentPlus`
* Kill task version support.
Kill tasks by default kill all versions of unused segments in the specified
interval. Users wanting to delete specific versions (for example, data compliance
reasons) and keep rest of the versions can specify the optional version in the
kill task payload.
* Formatting changes.
* Multi version tests in RetrieveSegmentsActionsTest
Sort of like method-level parameterized tests.
* Address review feedback
* Accept a list of versions instead of a single version.
Support multiple versions.
* Tests for multiple versions.
* Update docs
* Cleanup
* Address review comments.
Retain the old interface method and make it default and route it to
the method with nullable versions variant. Update usages to use the
default method where versions doesn't matter.
* Remove versions from retreive used segments action.
* Some updates.
* Apply suggestions from code review

Handling array with boolean literals like ARRAY[true, false]
Druid appears to be able to convert an array with boolean expressions like this array[added=deleted, added=delta] into a numeric array of 0 and 1: select array[added=deleted, added=delta] from wikipedia
However, select array[true, false] from wikipedia doesn't work.
This PR fixes this.
Changes:
- Use an actual SqlSegmentsMetadataManager instead of TestSqlSegmentsMetadataManager
- Simplify TestSegmentsMetadataManager
- Add a test for large interval segments.
The previously used GCS API client library returned last update time for objects directly in milliseconds. The new library returns it in OffsetDateTime format which was being converted to seconds and stored against the object. This fix converts the time back to ms before storing it.

Changes:
Improve `SqlSegmentsMetadataManager`
- Break the loop in `populateUsedStatusLastUpdated` before going to sleep if there are no more segments to update
- Add comments and clean up logs
Refactor `SqlSegmentsMetadataManagerTest`
- Merge `SqlSegmentsMetadataManagerEmptyTest` into this test
- Add method `testPollEmpty`
- Shave a few seconds off of the tests by reducing poll duration
- Simplify creation of test segments
- Some renames here and there
- Remove unused methods
- Move `TestDerbyConnector.allowLastUsedFlagToBeNull` to this class
Other minor changes
- Add javadoc to `NoneShardSpec`
- Use lambda in `SqlSegmentMetadataPublisher`
Recently this test started other tests from executing by triggering a bug somewhere in surefire.
This patch disables the testcases in case of non-sql compat mode.
While converting Sequence<ScanResultValue> to Sequence<Frames>, when maxSubqueryBytes is enabled, we batch the results to prevent creating a single frame per ScanResultValue. Batching requires peeking into the actual value, and checking if the row signature of the scan result’s value matches that of the previous value.
Since we can do this indefinitely (in the worst case all of them have the same signature), we keep fetching them and accumulating them in a list (on the heap). We don’t really know how much to batch before we actually write the value as frames.
The PR modifies the batching logic to not accumulate the results in an intermediary list
Changes:
- Add visibility into number of segments read/published by each parallel compaction
- Add new fields `segmentsRead`, `segmentsPublished` to `IngestionStatsAndErrorsTaskReportData`
- Update `ParallelIndexSupervisorTask` to populate the new stats

BaseNodeRoleWatcher counts down cacheInitialized after a timeout, but also sets some flag that it was a timed-out initialization. and call nodeViewInitializationTimedOut (new method on listeners) instead of nodeViewInitialized. Then listeners can do what is most appropriate with this information.
