IMPALA-9077: Remove scalable admission control configs
Removed the 3 scalable configs added in IMPALA-8536:
- Max Memory Multiple
- Max Running Queries Multiple
- Max Queued Queries Multiple
This patch removes the functionality related to those configs but
retains the additional test coverage and cleanup added in
IMPALA-8536. This removal is to make it easier to enhance
Admission Control using Executor Groups which has turned out to
be a useful building block.
Testing:
Ran core tests.
