Writing a test for this is tricky. There is enough coverage for
functional tests. Only concern is performance, but there is enough
logging for it to detect timed out/badly performing sync calls.
Additionally, this patch decouples the ZK event processing into it's
own thread rather than doing it in the EventThread's context. That
avoids deadlocks and stalls of the event thread.

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
referenced
- 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'.

will delay old MOB file cleanup until per-region compaction has managed
to compact each region at least once so that used mob hfile metadata can
be gathered.

Makes MergeTableRegionsProcedure do more than just two regions at a
time. Compatible as MTRP was done considering one day it'd do more than
two at a time.
Changes hardcoded assumption that merge parent regions are named
mergeA and mergeB in a column on the resultant region. Instead
can have N columns on the merged region, one for each parent
merged. Column qualifiers all being with 'merge'.
Most of code below is undoing the assumption that there are two
parents on a merge only.
Refactor of CatalogJanitor so it generates a
Report on the state of hbase:meta when it runs. Also
refactor so CJ runs even if RIT (previous it would
punt on running if RIT) so it can generate a 'Report'
on the interval regardless. If RIT, it just doesn't
go on to do the merge/split GC as it used to.
If report finds an issue, dump as a WARN message
to the master log.
Follow-on is to make the Report actionable/available
for the Master to pull when it goes to draw the hbck
UI page (could also consider shipping the Report as
part of ClusterMetrics?)
Adds new, fatter Visitor to CJ, one that generates
Report on each run keeping around more findings as
it runs.

previous methods were randomly ordered in the class.
