* 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.
Related to #5522, FYI @a2l007.
* Prohibit some guava collection APIs and use JDK APIs directly

* 1. Mysql default transaction isolation is REPEATABLE_READ, treat it as READ_COMMITTED will reduce insert id conflict.
2. Add an index to 'dataSource used end' is work well for the most of scenarios(get recently segments), and it will speed up sync add pending segments in DB.
3. 'select and insert' is not need within transaction.

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.
