Change subject: IMPALA-12264: Add limit on number of HS2 sessions per user. ...................................................................... IMPALA-12264: Add limit on number of HS2 sessions per user. Add a new flag --max_hs2_sessions_per_user which sets a limit on the number of Hiveserver2 sessions that can be concurrently opened by a user on a coordinator. By default this value is -1, which disables the new feature. An attempt to open more sessions than the new flag value results in an error. This is implemented by maintaining a map of users to a count of HS2 sessions. If the per-user HS2 session counts are being limited in this way, then the per-user counts are visible on the /sessions page of the webui. Add a new test case in test_session_expiration.py.
