IMPALA-6793: Fix empty metadata after statestore restarts

IMPALA-5990 introduced a bug where restarting the statestore
deterministically clears the metadata without ever coming back. The
cause of the bug is a wrong condition used by catalog to detect the
restart of statestore.

A custom cluster regression test is added. The process restarting
utility function in the custom cluster test is changed into using
shell=True in popen.
