Two test_udfs.py tests (test_native_functions_race and
test_concurrent_jar_drop_use) spawn dozens of connections to
test Impala behavior under concurrency. These connections
use up frontend service threads and can cause shell tests
to timeout when trying to connect.
This moves both tests to a new TestUdfConcurrency custom
cluster test. The new custom cluster test uses a larger
fe_service_threads value to allow full concurrency. The
tests run serially and cannot impact other tests.
This also reduces the test dimensions for test_native_functions_race
so that it runs one configuration rather than eight.
