Commit 7dbdcfb9afa5928b1406527870ad197c72600cc6 in impala's branch

IMPALA-11989: ImpalaRuntimeException if Kudu and Impala use different HMS
Added a startup flag 'enable_kudu_impala_hms_check' which is used to
flag an error if Kudu and Impala are using different HMS instance(s).
The default behavior in Impala is not changed and the default value of
the new flag is true.
The check itself could be improved in future to ensure that the backend
store used by HMS is same. For now allowing a config option to disable
the check where it makes sense seems like a good short term solution.

> Kudu and Impala could use different HMS instances such that both these HMS
