* Add a section calling out our categorical lack of support for
non-LTS Java versions.
* Provide clarification as to the meaning of the 'red x' in our
support matrix.
* Transpose the support matrix to have HBase releases along the x-axis
and Java releases along the y-axis, because there are more Java
releases than HBase release categories.
* Update the JDK11 status in the matrix.
* Add a note qualifying our JDK11 support.

This one surfaced as a flake test but turns out to be a legit bug
in FIFOCompaction code. FifoCompaction does not check if an empty
store file is already being compacted by an in-flight compaction
request and still enqueues. It can potentially race with a running
compaction (as in this test case, see jira for the exact exception).
Fixes the edge case and cleans up the test code a bit.

Trying to make doc changes is pretty awful, with lines running on for
hundreds of columns. At least for this time, clean up with line breaks
where asciidoc will let us.

Simplify our Normalizer story to have just a single, configurable
implementation.
* fold the features of `MergeNormalizer` into
`SimpleRegionNormalizer`, removing the intermediate abstract class.
* configuration keys for merge-only features now share a common
structure.
* add configuration to selectively disable normalizer split/merge
operations.
* `RegionNormalizer` now extends `Configurable` instead of creating a
new instance of `HBaseConfiguration` or snooping one off of other
fields.
* avoid the extra RPCs by using `MasterServices` instead of
`MasterRpcServices`.
* boost test coverage of all the various flags and feature
combinations.

This utility is useful for any module that wants to detect
dynamic config changes. Having it to hbase-common makes it
accessible to all the other modules.

Some javadoc invocations require that annotations we reference can have any
classes they reference resolved. This includes annotations _they_ have,
even though annotations are normally optional.
In some cases this showed up as javax.annotation.meta.TypeQualifierNickname
not found, because some findbugs annotations use it. Other times it was
javax.annotation.concurrent.Immutable not found, because some old guava
versions use it.
(updated for master branch by doing the config in report config instead of plugin)
