* PoolMap does not discard any elements anymore. If an element is put,
it always stores it. The reason: it stores expensive resources (rpc
connections) which would lead to resource leak if we simple discard it.
RpcClients can reference netty ByteBufs which are reference counted.
Resource cleanup is done by AbstractRpcClient.cleanupIdleConnections().
* PoolMap does not implement Map interface anymore, so ensuring
thread-safety has become easier. Put method is replaced with getOrCreate().
* ThreadLocalPool doesn't use ThreadLocal class anymore. It stores
resources on thread basis, but it doesn't remove values when a thread
exits. Again, proper cleanup is done by cleanupIdleConnections().

This PR is a follow-up of HBASE-25181 (#2539), where several issues were
discussed on the PR:
1. Currently we use PBKDF2WithHmacSHA1 key generation algorithm to generate a
secret key for HFile / WalFile encryption, when the user is defining a string
encryption key in the hbase shell. This algorithm is not secure enough and
not allowed in certain environments (e.g. on FIPS compliant clusters). We are
changing it to PBKDF2WithHmacSHA384. It will not break backward-compatibility,
as even the tables created by the shell using the new algorithm will be able
to load (e.g. during bulkload / replication) the HFiles serialized with the
key generated by an old algorithm, as the HFiles themselves already contain
the key necessary for their decryption.
Smaller issues fixed by this commit:
2. Improve the documentation e.g. with the changes introduced by HBASE-25181
and also by some points discussed on the Jira ticket of HBASE-25263.
3. In EncryptionUtil.createEncryptionContext the various encryption config
checks should throw IllegalStateExceptions instead of RuntimeExceptions.
4. Test cases in TestEncryptionTest.java should be broken down into smaller
tests.
5. TestEncryptionDisabled.java should use ExpectedException JUnit rule to
validate exceptions.

Expose an argument on the `count` command which is passed to the
`setCacheBlocks` method on the Scan which the count command uses.
This is a quick and dirty approach to read all of the blocks for a table
into the block cache.

Clean up the read replica of META doc. Introduce the new read replica
liveness on META and the new 'LoadBalance' feature (with warnings).
General edit.
It adds load balance support for meta lookup in AsyncTableRegionLocator.
The existing meta replica mode is renamed as "HedgedRead", client sends scan request to the primary meta replica region first,
if response is not back within a configured amount of time, it will send scan requests to all meta replica regions and
take the first response. On top of the existing mode, a new mode "LoadBalance" is introduced. In this mode, client first
choose a meta replica region to send scan request. If the response is stale, it may send the request to another meta replica region or
the primary region. In this mode, meta scan requests are load balanced across all replica regions with the primary mode as
the ultimate source of truth.
Two new config knobs are added:
1. hbase.locator.meta.replicas.mode
Valid options are "None", "HedgedRead" and "LoadBalance", they are case insensitive. The default mode is "None".
2. hbase.locator.meta.replicas.mode.loadbalance.selector
The load balance alogrithm to select a meta replica to send the requests.
Only org.apache.hadoop.hbase.client.CatalogReplicaLoadBalanceReplicaSimpleSelector.class
is supported for now, which is the default as well. The algorithm works as follows:
a. Clients select a randome meta replica region to send the requests if there is no entry for the location in the stale
location cache.
b. If the location from one meta replica region is stale, a stale entry will be created in the statle location cache
for the region.
c. Clients select the primary meta region if the location is in the stale location cache.
d. The stale location cache entries time out in 3 seconds.
If there is no "hbase.locator.meta.replicas.mode" configured, it will check the config knob "hbase.meta.replicas.use".
If "hbase.meta.replicas.use" is configured, the mode will be set to "HedgedRead".
For branch-2 support, it introduces support for ReversedScan over a specific non-default replica region, this is mainly
for load balance meta scan among all its replica regions.

* HBASE-25055 Add ReplicationSource for meta WALs; add enable/disable when hbase:meta assigned to RS
Fill in gap left by HBASE-11183 'Timeline Consistent region replicas - Phase 2 design'.
HBASE-11183 left off implementing 'async WAL Replication' on the hbase:meta
Table; hbase:meta Table could only do Phase 1 Region Replicas reading
the primary Regions' hfiles. Here we add 'async WAL Replication' to
hbase:meta so Replicas can be more current with the primary's changes.
Adds a 'special' ReplicationSource that reads hbase:meta WAL files and replicates
all edits to the configured in-cluster endpoint (Defaults to the
RegionReadReplicaEndpoint.class -- set hbase.region.replica.catalog.replication to
target a different endpoint implementation).
Set hbase.region.replica.replication.catalog.enabled to enable async WAL
Replication for hbase:meta region replicas. Its off by default.
The CatalogReplicationSource for async WAL Replication of hbase:meta does
NOT need to keep up WAL offset or a queue of WALs-to-replicate in the
replication queue store as is done in other ReplicationSource implementations;
the CatalogReplicationSource is for Region Replicas only. General
Replication does not replicate hbase:meta. hbase:meta Region Replicas reset
on crash of the primary replica so there is no need to 'recover'
replication that was running on the crashed server.
Because it so different in operation, the CatalogReplicationSource is bolted
on to the side of the ReplicationSourceManager. It is lazily
instantiated to match the lazy instantiation of the hbase:meta
WALProvider, created and started on the open of the first Region of an
hbase:meta table. Thereafter it stays up till the process dies, even if
all hbase:meta Regions have moved off the server, in case a hbase:meta
Region is moved back (Doing this latter simplifies the implementation)

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.
