IMPALA-13906: Change TestQueryConcurrency to regular query_test
TestQueryConcurrency run much slower when the test client changed from
beeswax to hs2. The reason is this test inject slowdown through backend
flag --stress_metadata_loading_pause_injection_ms=100000 that will
impact all queries. Changing test client to ImpylaHS2Connection will
cause this test run much slower because ImpylaHS2Connection populate its
default query options by running SET ALL query.
This patch speed up TestQueryConcurrency by changing it from
custom_cluster to regular query_test, using debug action to inject
slowdown, and lower the slowdown from 100s to 60s.
Added debug action EXECUTE_INTERNAL_REGISTERED to replace
stress_metadata_loading_pause_injection_ms flag.
Testing:
- Pass TestQueryConcurrency in exhaustive mode.
