IMPALA-4041: Limit catalog and admission control updates to coordinators With this commit we add the ability to limit catalog updates to a limited set of coordinator nodes. A new startup option, termed 'is_coordinator' is added to indicate if a node is a coordinator. Coordinators accept connections through HS2 and Beeswax interfaces and can also participate in query execution. Non-coordinator nodes do not receive catalog updates from the statestore, do not initialize a query scheduler and cannot accept Beeswax and HS2 client connections. Testing: - Added a custom cluster test that launches a cluster in which the number of coordinators is less than the cluster size and runs a number of smoke queries. - Successfully run exhaustive tests.
