* Properly set "identity" in query metrics.
This patch adds an "identity" field to QueryPlus and sets it in
QueryLifecycle when the query starts executing. This is important
because it allows it to be used for future QueryMetrics created
by that QueryPlus object.
We also add "identity" to the request-level QueryMetrics object
created in emitLogsAndMetrics.

Both were susceptible to the following conditions:
1. Two JVMs on the same machine (perhaps two peons) could conflict by one reading while the
other was writing, or by writing to the file at the same time.
2. One JVM could partially write a file, then crash, leaving a truncated file.
* Use StringUtils.format

The behavior is configurable through druid.extensions.useExtensionClassloaderFirst.
It is useful when extensions want to load a dependency different from one provided
by Druid, for example a different version of geoip or protobuf.
Also remove Guice annotations from LoadQueueTaskMaster, since it is
provided by CliCoordinator, so Guice does not need to know how to
build one directly.
Code changes:
- In the lookup-based extractionFns, inherit injective property from
the lookup itself if not specified.
Doc changes:
- Add a "Query execution" section to the lookups doc explaining how
injective lookups and their optimizations work.
- Remove scary warnings against using registeredLookup extractionFns.
They are necessary and important since they work with filters and
function cascades -- two things that the dimension specs do not do.
They deserve to be first class citizens.
- Move the "registeredLookup" fn above the "lookup" fn. It's probably
more commonly used, so the docs read better this way.
* just renaming of SegmentChangeRequestHistory etc
* additional change history refactoring changes
* WorkerTaskManager a replica of WorkerTaskMonitor

* Introducing HttpRemoteTaskRunner
* Additional Worker side updates
* Fix broken KafkaEmitterConfig parsing
This was a regression introduced in
https://github.com/druid-io/druid/pull/4722
KafkaEmitterConfig property names have dot(.) in the name of properties
and JsonConfigurator behavior was changed to not support that.
Added a test and fixed parsing of properties that have dot(.) in
property names

* update HttpServerInventoryViewTest to ensure that predicates are honored
* add docs for HttpServerInventoryView.defaultFilter
* change to javadoc style comment
* Deduplicate DataSegments contents (loadSpec's keys, dimensions and metrics lists as a whole) more aggressively; use ArrayMap instead of default LinkedHashMap for DataSegment.loadSpec, because they have only 3 entries on average; prune DataSegment.loadSpec on brokers

* Recognize 'not found' lookups in LookupReferencesManager.tryGetLookupListFromCoordinator(), by @egor-ryashin
* 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.

and ingestSegment firehose.

* 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.

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
