This commit adds table name to the logging context when
StochasticLoadBalancer is configured "per table". Added some
test coverage with per-table balancer enabled and manually
verified the logs to make sure the table name is formatted
correctly.

(cherry picked from commit 06ff478674)
Make it so hbase:meta can be altered. TableState for hbase:meta
is kept in Master. State is in-memory transient so if Master
fails, hbase:meta is ENABLED again. 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 prevented our being able to edit
hbase:meta. At minimmum, need to add in a bunch of WARNING.
TODO: Tests, more clarity around hbase:meta table state, and undoing
references to hard-coded hbase:meta regioninfo.
M hbase-client/src/main/java/org/apache/hadoop/hbase/MetaTableAccessor.java
Throw illegal access exception if you try to use MetaTableAccessor
getting state of the hbase:meta table.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/ConnectionImplementation.java
For table state, go to master rather than go to meta direct. Going
to meta won't work for hbase;meta state. Puts load on Master.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
Change isTableDisabled/Enabled implementation to ask the Master instead.
This will give the Master's TableStateManager's opinion rather than
client figuring it for themselves reading meta table direct.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/RawAsyncHBaseAdmin.java
TODO: Cleanup in here. Go to master for state, not to meta.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/ZKAsyncRegistry.java
Logging cleanup.
M hbase-client/src/main/java/org/apache/hadoop/hbase/zookeeper/ZNodePaths.java
Shutdown access.
M hbase-server/src/main/java/org/apache/hadoop/hbase/TableDescriptors.java
Just cleanup.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/TableStateManager.java
Add state holder for hbase:meta.
Removed unused methods.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionStateStore.java
Shut down access.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/procedure/DisableTableProcedure.java
Allow hbase:meta to be disabled.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/procedure/EnableTableProcedure.java
Allow hbase:meta to be enabled.

Space quotas has a feature which intends to avoid enacting a space quota
violation policy when only a subset of the Regions for that Table have
reported their space usage (under the assumption that we cannot make an
informed decision if we do not include all regions in our calculations).
This had the unintended side-effect, when a table is disabled as a part
of a violation policy, of causing the regions for that table to not be
reported which disables the violation policy and enables the table.
Need to make sure that when a table is disabled because of a violation
policy that the code does not automatically move that table out of
violation because region sizes are not being reported (because those
regions are not open).

There was a bug in which we would not drop the RegionSizes
for a table in a namespace, where the namespace had a quota
on it. This allowed a scenario in which recreation of a table
inside of a namespace would unintentionally move into violation
despite the table being empty. Need to make sure the RegionSizes
are dropped on table deletion if there is _any_ quota applying
to that table.

During startup, it's possible that quotas are enabled but the Master has
not yet created the hbase:quotas table.
