This reverts commit bfa45841251e3224e3fbb07599ae5dd6791b2846.
This is not ready yet. There are some code paths remaining where store
configuration (CompoundConfiguration) is not passed into the block decoding
context. Found with additional integration tests.

This change introduces provided compression codecs to HBase as
new Maven modules. Each module provides compression codec support
that formerly required Hadoop native codecs, which in turn relies
on native code integration, which may or may not be available on
a given hardware platform or in an operational environment. We
now provide codecs in the HBase distribution for users whom for
whatever reason cannot or do not wish to deploy the Hadoop native
codecs.

We introduced EnvironmentEdgeManager as a way to inject alternate clocks
for unit tests. In order for this to be effective, all callers that would
otherwise use System.currentTimeMillis() must call
EnvironmentEdgeManager.currentTime() instead, except the implementers of
EnvironmentEdge.

This revert of a revert reapplies the PR; the original application was
missing the HBASE JIRA #; thats why it was reverted and then reapplied
w/ the JIRA # added.
This reverts commit 16fe1e95ec5ca5528adc8c0aa7dc00f18c3f014f.
Revert of the revert -- re-applying HBASE-25449 with a change
of renaming the test hdfs XML configuration file as it was adversely
affecting tests using MiniDFS
This reverts commit c218e576fe54df208e277365f1ac24f993f2a4b1.

Wire up the `ConfigurationObserver` chain for
`RegionNormalizerManager`. The following configuration keys support
hot-reloading:
* hbase.normalizer.throughput.max_bytes_per_sec
* hbase.normalizer.split.enabled
* hbase.normalizer.merge.enabled
* hbase.normalizer.min.region.count
* hbase.normalizer.merge.min_region_age.days
* hbase.normalizer.merge.min_region_size.mb
Note that support for `hbase.normalizer.period` is not provided
here. Support would need to be implemented generally for the `Chore`
subsystem.

The core change here is to the loop in
`SimpleRegionNormalizer#computeMergeNormalizationPlans`. It's a nested
loop that walks the table's region chain once, looking for contiguous
sequences of regions that meet the criteria for merge. The outer loop
tracks the starting point of the next sequence, the inner loop looks
for the end of that sequence. A single sequence becomes an instance of
`MergeNormalizationPlan`.

Add a create simple kdc server utility that will start a kdc server and
if a bindexception, create a new one on a new random port in hbase-common.
Add new BoundSocketMaker helpful when trying to manufacture
BindExceptions because of port clash.
Change thrift and http kdc tests to use this new utility (removes
code duplication around kdc server setup).
