Description

On HBASE-12566, lhofhansl proposed:

Maybe we can have a Region interface that is to HRegion is what Store is to HStore. Store marked with @InterfaceAudience.Private but used in some coprocessor hooks.

By example, now coprocessors have to reach into HRegion in order to participate in row and region locking protocols, this is one area where the functionality is legitimate for coprocessors but not for users, so an in-between interface make sense.

In addition we should promote Store's interface audience to LimitedPrivate(COPROC).
