IMPALA-8990: Fix flakiness in test_set_request_pool

This patch fixes flakiness in test_set_request_pool where one of the
test cases expects a query to already be accounted for in a resource
pool but sometimes gets into a state where it runs before the
previous query passes admission control. This fixes the issue by
waiting for the previous query to clear admission control before
attempting to run the aforementioned failing query.

Testing:
- Ran test locally in a loop for an hour to flush out flakiness.

Welcome to Impala

Lightning-fast, distributed SQL queries for petabytes of data stored in Apache Hadoop clusters.

Impala is a modern, massively-distributed, massively-parallel, C++ query engine that lets you analyze, transform and combine data from a variety of data sources:

  • Best of breed performance and scalability.
  • Support for data stored in HDFS, Apache HBase, Apache Kudu, Amazon S3, Azure Data Lake Storage, Apache Hadoop Ozone and more!
  • Wide analytic SQL support, including window functions and subqueries.
  • On-the-fly code generation using LLVM to generate lightning-fast code tailored specifically to each individual query.
  • Support for the most commonly-used Hadoop file formats, including Apache Parquet and Apache ORC.
  • Support for industry-standard security protocols, including Kerberos, LDAP and TLS.
  • Apache-licensed, 100% open source.
