IMPALA-12281: Disallow unsetting REQUEST_POOL if it is set by client

IMPALA-12056 enable child query to unset REQUEST_POOL if it is set by
Frontend.java as part of executor group selection. However, the
implementation miss to setRequest_pool_set_by_frontend(false) if
REQUEST_POOL is explicitly set by client request through impala-shell
configuration. This cause child query to always unset REQUEST_POOL if
parent query was executed via impala-shell. This patch fix the issue by
checking query options that comes from client.

This patch also tidy up null and empty REQUEST_POOL checking by using
StringUtils.isNotEmpty().

Testing:
- Add testcase in test_query_cpu_count_divisor_default
