Commit decb79d0328f6b4daa74ca4228291571e7b4b668 in impala's branch
refs/heads/master from Aman Sinha

IMPALA-10518: Add ImpalaServer interface to retrieve executor membership.
This patch adds an interface to ImpalaServer to retrieve the current
executor membership snapshot from impalad for use by an external
frontend. This involves sending a thrift request to impalad and
receiving a thrift response. Refactored some code in exec-env into
a separate function in the impala namespace which makes it easier to
populate the needed information for an external frontend.
Testing:
- Ran selected tests for sanity check (no impact is expected
since this is adding a new interface):
- Frontend tests (PlannerTest, CardinalityTest)
- Backend tests under custom_cluster/test_executor_groups.py
- Manually tested with external frontend to ensure it gets
the executor membership snapshot.
