Andrew Purtell commented on HBASE-14122:
----------------------------------------
Tested with the shell talking to a master with the change applied and without.
Works as expected. Added some simple cases to the security coprocessor unit
tests to verify the answer includes their capabilities when installed.

> Add a client API for determining if the server side supports cell level
> security.
> Ask the master, assuming as we do in many other instances that the master and
> regionservers all have a consistent view of site configuration.
> Return {{true}} if all features required for cell level security are present,
> {{false}} otherwise, or throw {{UnsupportedOperationException}} if the master
> does not have support for the RPC call.
