Adds "hbase.master.executor.merge.dispatch.threads" and defaults to 2.
Also adds additional logging that includes the number of split plans
and merge plans computed for each normalizer run.

Network identities should be bound late. Remote addresses should be
resolved at the last possible moment, just before connect(). Network
identity mappings can change, so our code should not inappropriately
cache them. Otherwise we might miss a change and fail to operate normally.
Revert "HBASE-14544 Allow HConnectionImpl to not refresh the dns on errors"
Removes hbase.resolve.hostnames.on.failure and related code. We always
resolve hostnames, as late as possible.
Preserve InetSocketAddress caching per RPC connection. Avoids potential
lookups per Call.
Replace InetSocketAddress with Address where used as a map key. If we want
to key by hostname and/or resolved address we should be explicit about it.
Using Address chooses mapping by hostname and port only.
Add metrics for potential nameservice resolution attempts, whenever an
InetSocketAddress is instantiated for connect; and metrics for failed
resolution, whenever InetSocketAddress#isUnresolved on the new instance
is true.
* Use ServerName directly to build a stub key
* Resolve and cache ISA on a RpcChannel as late as possible, at first call
* Remove now invalid unit test TestCIBadHostname
We resolve DNS at the latest possible time, at first call, and do not
resolve hostnames for creating stubs at all, so this unit test cannot
work now.

HBase UI is currently using in bootstrap 3.3.7. This version is vulnerable to 4
medium CVEs (CVE-2018-14040, CVE-2018-14041, CVE-2018-14042, and CVE-2019-8331).
Details on all the bootstrap versions and vulnerabilities is
here: https://snyk.io/vuln/npm:bootstrap
Upgrading to bootstrap 4 would be nice, but potentially more work to do. We
should at least upgrade to the latest bootstrap 3, which is 3.4.1 currently.

If hbase.regionserver.close.wait.abort is set to true, interrupt RPC
handler threads holding the region close lock.
Until requests in progress can be aborted, wait on the region close lock for
a configurable interval (specified by hbase.regionserver.close.wait.time.ms,
default 60000 (1 minute)). If we have failed to acquire the close lock after
this interval elapses, if allowed (also specified by
hbase.regionserver.close.wait.abort), abort the regionserver.
We will attempt to interrupt any running handlers every
hbase.regionserver.close.wait.interval.ms (default 10000 (10 seconds)) until
either the close lock is acquired or we reach the maximum wait time.
Define a subset of region operations as interruptible. Track threads holding
the close lock transiting those operations. Set the thread interrupt status
of tracked threads when trying to close the region. Use the thread interrupt
status where safe to break out of request processing.
