IMPALA-4465: Don't hold process wide lock while serializing Runtime Profile in GetRuntimeProfileStr() This patch changes the code so that the query_exec_state_map_lock_ is not held while serializing the RuntimeProfile, since that is a pretty expensive operation and happens at least once per query. This change makes a lot of client calls have less lock contention including Webserver calls and query registration/unregistration.
