When hitting NotServingRegionException, we will check if the table is disabled.

> Task that comes of parent issue. Parent makes it so we go via Master to
> figure state of a table. It is the authority and since the parent issues adds
> being able to enable/disable hbase:meta, table state is now in two places --
> in hbase:meta table... and elsewhere for the hbase:meta's state. Rather than
> have client go to two locations dependent on which table is being asked
> about, parent made it so we went to master. Parent allows that this puts more
> load on the Master. [~zhangduo] brings up the valid concern that it might be
> too much or that dependent on the Master for state puts Master too much
> in-line with read/writes.
> This issue is a survey to figure how much load and how much state-in-master
> could mess up inline read/writes.
