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".
warmupRegion called by Master on Region move will instatiate
the meta WALProvider as part of its action making it so
it is already created by the time we go to open the
hbsae:meta Region. Accommodate meta walProvider
being already up.

* 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-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java
Read configuration to see if we need to wait on setting a Region read-enabled

Pass WALFactory to Replication instead of WALProvider. WALFactory has all
WALProviders in it, not just the user-space WALProvider. Do this so
ReplicationService has access to all WALProviders in the Server (To be
exploited by the follow-on patch in HBASE-25055)
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.

Prior to this patch hbase always used the MD5 hash algorithm to store a hash for encryption keys.
This hash is needed to verify the secret key of the subject. (e.g. making
sure that the same secrey key is used during encrypted HFile read and write).
The MD5 algorithm is considered weak, and can not be used in some
(e.g. FIPS compliant) clusters.
In this patch we:
- add a config parameter to globally enable/disable column family encryption (def enabled)
- introduce a backward compatible way of specifying the hash algorithm.
This enable us to use newer and more secure hash algorithms like SHA-384
or SHA-512 (which are FIPS compliant).
- add a config parameter to fail if an hfile is encountered that uses a
different hash algorithm than the one currently configured to ease validation after
migrating key hash algorithms (def disabled)

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.

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`.
