A miscellaney. Add extra logging to help w/ debug to a bunch of tests.
Fix some issues particular where we ran into mismatched filesystem
complaint. Some modernizations, removal of unnecessary deletes
(especially after seeing tests fail in table delete), and cleanup.
Recategorized one tests because it starts four clusters in the one
JVM from medium to large. Finally, zk standalone server won't come
on occasion; added debug and thread dumping to help figure why (
manifests as test failing in startup saying master didn't launch).

There were a couple of issues.
- There was a leak of a file descriptor for hbck lock file. This
was contributing to all the "ConnectionRefused" stack traces since
it was trying to renew lease for an already expired mini dfs cluster.
This issue was there for a while, just that we noticed it now.
- After upgrade to JUnit 4.13, it looks like the behavior for test
timeouts has changed. Earlier the timeout seems to have applied for
each parameterized run, but now it looks like it is applied across
all the runs.
This patch fixes both the issues.

- MOB compaction is now handled in-line with per-region compaction on region
servers
- regions with mob data store per-hfile metadata about which mob hfiles are

- admin requested major compaction will also rewrite MOB files; periodic RS
initiated major compaction will not
- periodically a chore in the master will initiate a major compaction that
will rewrite MOB values to ensure it happens. controlled by
'hbase.mob.compaction.chore.period'. default is weekly
- control how many RS the chore requests major compaction on in parallel
with 'hbase.mob.major.compaction.region.batch.size'. default is as
parallel as possible.
- periodic chore in master will scan backing hfiles from regions to get the
set of referenced mob hfiles and archive those that are no longer
referenced. control period with 'hbase.master.mob.cleaner.period'
- Optionally, RS that are compacting mob files can limit write
amplification by not rewriting values from mob hfiles over a certain size
limit. opt-in by setting 'hbase.mob.compaction.type' to 'optimized'.
control threshold by 'hbase.mob.compactions.max.file.size'.

The Hadoop AccessControlList allows us to specify admins of the webUI
via a list of users and/or groups. Admins of the WebUI can mutate the
system, potentially seeing sensitive data or modifying the system.
hbase.security.authentication.spnego.admin.users is a comma-separated
list of users who are admins.
hbase.security.authentication.spnego.admin.groups is a comma-separated
list of groups whose membership are admins. Either of these
configuration properties may also contain an asterisk (*) which denotes
"any entity" (e.g user, group).
Previously, when a user was denied from some endpoint that was
designated for admins, they received an HTTP/401. In this case, it is
more correct to return HTTP/403 as they were correctly authenticated,
but they were disallowed from fetching the given resource. This commit
incorporates this change.
hbase.security.authentication.ui.config.protected also exists for users
who have sensitive information stored in the Hadoop service
configuration and want to limit access to this endpoint. By default,
the Hadoop configuration endpoint is not protected and any
authenticated user can access it.
The test is based off of work by Nihal Jain in HBASE-20472.

Make it so hbase:meta can be altered. TableState for hbase:meta
was hardcoded ENABLED. Make it dynamic. State is now kept in
current active Master. It is transient so falls back to default
if Master crashes. Add to registry a getMetaTableState
which reads mirrored state from zookeeper (NOT from Master and
defaults ENABLED if no implementation or error fetching state).
hbase:meta schema will be bootstrapped from the filesystem.
Changes to filesystem schema are atomic so we should be ok if
Master fails mid-edit (TBD). Undoes a bunch of guards that
