* Fix havingSpec on complex aggregators.
- Uses the technique from #4883 on DimFilterHavingSpec too.
- Also uses Transformers from #4890, necessitating a move of that and other
related classes from druid-server to druid-processing. They probably make
more sense there anyway.
- Adds a SQL query test.
Fixes#4957.
* Remove unused import.
* Introduce "transformSpec" at ingest-time.
It accepts a "filter" (standard query filter object) and "transforms" (a
list of objects with "name" and "expression"). These can be used to do
filtering and single-row transforms without need for a separate data
processing job.
The "expression" fields use the same expression language as other
expression-based feature.
* Remove forbidden api.
* Fix compile error.
* Fix tests.
* Some more changes.
- Add nullable annotation to Firehose.nextRow.
- Add tests for index task, realtime task, kafka task, hadoop mapper,
and ingestSegment firehose.
* Fix bad merge.
* Adjust imports.
* Adjust whitespace.
* Make Transform into an interface.
* Add missing annotation.
* Switch logger.
* Switch logger.
* Adjust test.
* Adjustment to handling for DatasourceIngestionSpec.
* Fix test.
* CR comments.
* Remove unused method.
* Add javadocs.
* More javadocs, and always decorate.
* Fix bug in TransformingStringInputRowParser.
* Fix bad merge.
* Fix ISFF tests.
* Fix DORC test.
* Fix binary serialization in caching
The previous caching code just concatenated a list of objects into a
byte array -- this is actually not valid because jackson-databind uses
enumerated references to strings internally, and concatenating multiple
binary serialized objects can throw off the references.
This change uses a single JsonGenerator to serialize the object list
rather than concatenating byte arrays.
* remove unused imports
* introducing CuratorLoadQueuePeon
* HttpLoadQueuePeon based off of current code
* Revert "Remove SegmentLoaderConfig.numLoadingThreads config (#4829)"
This reverts commit d8b3bfa63c.
* SegmentLoadDropHandler copy/pasted from ZkCoordinator
* Revert "1-based counts in ZkCoordinator (#4917)"
This reverts commit e725ff4146.
* remove non-zk part from ZkCoordinator
* remove zk part from SegmentLoadDropHandler
* additional changes for segment load/drop management with http
* address review comments
* add some more logs
* Execs class is moved
* Only consider loaded replicants when computing replication status.
This affects the computation of segment/underReplicated/count and
segment/unavailable/count, as well as the loadstatus?simple and
loadstatus?full APIs.
I'm not sure why they currently consider segments in the load
queues, but it would make more sense to me if they only considered
segments that are actually loaded.

* Add identity to query metrics, logs.
Also fix a bug where unauthorized requests would not emit any logs or metrics,
and instead would log a "Tried to emit logs and metrics twice" warning.
Also rename QueryResource's "getServer" to "cancelQuery", because that's what
it does.
* Do not emit identity by default.
* remove ServerConfig from DruidNode as all information needs to be present in DruidNode serialized form
* sanitize output of /druid/coordinator/v1/cluster endpoint
