IMPALA-8731: Balance queries across multiple executor groups
This patch adds a new admission control policy that attempts to
balance queries across multiple executor groups belonging to the
same request pool based on available memory and slots in each
executor group. This feature can be enabled by setting the startup
flag '-balance_queries_across_executor_groups=true'. The setting is
off by default.
Testing:
- Add e2e tests to verify the default policy and the new policy.
