Gagan Goel 712d34a407 MCOL-4988 Table lock remained after DML failure due to DBRM in read-only mode. 
DMLProcessor functor earlier did not check if the DBRM was in read-only mode.
This allowed DML statements to continue execution to the point where it locks
the table and then sends the statement down to the WriteEngineServer, which
ultimately returns back in an error state to DMLProc when it fails to perform
BRM updates due to DBRM in read-only mode. This caused a lingering table lock
in the system which could only be cleared on a system restart.

As a fix, we add a check in the DMLProcessor functor to detect if DBRM is in
read only mode, and if so, return back early in the execution of the DML
statement.
