* Fix missing default config in some calls to coordinator dynamic configs.
The lack of a default config meant that if someone called an API
_without_ a default config before one _with_ a default config, then
the default value would get stuck at null instead of the intended
default value. I noticed this in a cluster where calling /druid/coordinator/v1/config
before a coordinator had fully started up would lead to NPEs during
DruidCoordinatorRuleRunner.
This patch makes the default configs consistent across all calls.

This PR allows to control the fields in `RequestLogEvent`, emitted in `EmittingRequestLogger`. In our case, we want to get rid of the `intervals` fields of the query objects that are a part of `DefaultRequestLogEvent`. They are enormous (thousands of segments) and not useful.

This PR accumulates many refactorings and small improvements that I did while preparing the next change set of https://github.com/druid-io/druid/projects/2. I finally decided to make them a separate PR to minimize the volume of the main PR.
Some of the changes:
- Renamed confusing "Generic Column" term to "Numeric Column" (what it actually implies) in many class names.
- Generified `ComplexMetricExtractor`
* Added backpressure metric
* Updated channelReadable to AtomicBoolean and fixed broken test
* Moved backpressure metric logic to NettyHttpClient
* Fix placement of calculating backPressureDuration
* Add support targetCompactionSizeBytes for compactionTask
* fix test
* fix a bug in keepSegmentGranularity
* fix wrong noinspection comment
* address comments
The indexes introduced in #6348 were on the wrong table. The tests
did not catch them due to retries on the create table steps (the
first try created the table but not the bogus indexes; the second
try noticed that the table already existed and did nothing). This
patch doesn't fix the issue with the tests, since the best way to
do that would be to do the table and index creation in a
transaction; but, this is not supported by all of our supported
database engines.
* Adding licenses and enable apache-rat-plugi.

* 'suspend' and 'resume' support for kafka indexing service
changes:
* introduces `SuspendableSupervisorSpec` interface to describe supervisors which support suspend/resume functionality controlled through the `SupervisorManager`, which will gracefully shutdown the supervisor and it's tasks, update it's `SupervisorSpec` with either a suspended or running state, and update with the toggled spec. Spec updates are provided by `SuspendableSupervisorSpec.createSuspendedSpec` and `SuspendableSupervisorSpec.createRunningSpec` respectively.
* `KafkaSupervisorSpec` extends `SuspendableSupervisorSpec` and now supports suspend/resume functionality. The difference in behavior between 'running' and 'suspended' state is whether the supervisor will attempt to ensure that indexing tasks are or are not running respectively. Behavior is identical otherwise.
* `SupervisorResource` now provides `/druid/indexer/v1/supervisor/{id}/suspend` and `/druid/indexer/v1/supervisor/{id}/resume` which are used to suspend/resume suspendable supervisors
* Deprecated `/druid/indexer/v1/supervisor/{id}/shutdown` and moved it's functionality to `/druid/indexer/v1/supervisor/{id}/terminate` since 'shutdown' is ambiguous verbage for something that effectively stops a supervisor forever
* Added ability to get all supervisor specs from `/druid/indexer/v1/supervisor` by supplying the 'full' query parameter `/druid/indexer/v1/supervisor?full` which will return a list of json objects of the form `{"id":<id>, "spec":<SupervisorSpec>}`
* Updated overlord console ui to enable suspend/resume, and changed 'shutdown' to 'terminate'
* move overlord console status to own column in supervisor table so does not look like garbage
* spacing
* padding
* other kind of spacing
* fix rebase fail
* fix more better
* all supervisors now suspendable, updated materialized view supervisor to support suspend, more tests
* fix log
* Broker backpressure.
Adds a new property "druid.broker.http.maxQueuedBytes" and a new context
parameter "maxQueuedBytes". Both represent a maximum number of bytes queued
per query before exerting backpressure on the channel to the data server.
Fixes#4933.
* Fix query context doc.
* resolves#5898 by adding maxTotalRows to incremental publishing kafka index task and appenderator based realtime indexing task, as available in IndexTask
* address review comments
* changes due to review
* merge fail
* Rename io.druid to org.apache.druid.
* Fix META-INF files and remove some benchmark results.
* MonitorsConfig update for metrics package migration.
* Reorder some dimensions in inner queries for some reason.
* Fix protobuf tests.
* Fix all inspection errors currently reported.
TeamCity builds on master are reporting inspection errors, possibly
because there was a while where it was not running due to the Apache
migration, and there was some drift.
* Fix one more location.
* Fix tests.
* Another fix.
* Fix three bugs with segment publishing.
1. In AppenderatorImpl: always use a unique path if requested, even if the segment
was already pushed. This is important because if we don't do this, it causes
the issue mentioned in #6124.
2. In IndexerSQLMetadataStorageCoordinator: Fix a bug that could cause it to return
a "not published" result instead of throwing an exception, when there was one
metadata update failure, followed by some random exception. This is done by
resetting the AtomicBoolean that tracks what case we're in, each time the
callback runs.
3. In BaseAppenderatorDriver: Only kill segments if we get an affirmative false
publish result. Skip killing if we just got some exception. The reason for this
is that we want to avoid killing segments if they are in an unknown state.
Two other changes to clarify the contracts a bit and hopefully prevent future bugs:
1. Return SegmentPublishResult from TransactionalSegmentPublisher, to make it
more similar to announceHistoricalSegments.
2. Make it explicit, at multiple levels of javadocs, that a "false" publish result
must indicate that the publish _definitely_ did not happen. Unknown states must be
exceptions. This helps BaseAppenderatorDriver do the right thing.
* Remove javadoc-only import.
* Updates.
* Fix test.
* Fix tests.
* Cache: Add maxEntrySize config.
The idea is this makes it more feasible to cache query types that
can potentially generate large result sets, like groupBy and select,
without fear of writing too much to the cache per query.
Includes a refactor of cache population code in CachingQueryRunner and
CachingClusteredClient, such that they now use the same CachePopulator
interface with two implementations: one for foreground and one for
background.
The main reason for splitting the foreground / background impls is
that the foreground impl can have a more effective implementation of
maxEntrySize. It can stop retaining subvalues for the cache early.

* Remove some unnecessary task storage internal APIs.
- Remove MetadataStorageActionHandler's getInactiveStatusesSince and getActiveEntriesWithStatus.
- Remove TaskStorage's getCreatedDateTimeAndDataSource.
- Remove TaskStorageQueryAdapter's getCreatedTime, and getCreatedDateAndDataSource.
- Migrated all callers to getActiveTaskInfo and getCompletedTaskInfo.
This has one side effect: since getActiveTaskInfo (new) warns and continues when it
sees unreadable tasks, but getActiveEntriesWithStatus threw an exception when it
encountered those, it means that after this patch bad tasks will be ignored when
syncing from metadata storage rather than causing an exception to be thrown.
IMO, this is an improvement, since the most likely reason for bad tasks is either:
- A new version introduced an additional validation, and a pre-existing task doesn't
pass it.
- You are rolling back from a newer version to an older version.
In both cases, I believe you would want to skip tasks that can't be deserialized,
rather than blocking overlord startup.

False failures on Travis due to spurious timeout (in turn due to noisy
neighbors) is a bigger problem than legitimate failures taking too long
to time out. So it makes sense to extend timeouts.
* Fix SQL Server select query in createInactiveStatusesSinceQuery() method.
SQL server does not support LIMIT N in select queries. Instead it has TOP N to limiting number of query results.
And TOP N is already added in the select statement as per maxNumStatuses value.
* Add parentheses for TOP in SELECT statement as SQL Servers no longer support TOP without parentheses.
