cancel_query_and_validate_state is a helper method used to test query
cancellation with concurrent fetch. It is still use beeswax client by
default.
This patch change the test method to use HS2 protocol by default. The
changes include following:
1. Set TGetOperationStatusResp.operationState to
TOperationState::ERROR_STATE if returning abnormally.
2. Use separate MinimalHS2Client for
(execute_async, fetch, get_runtime_profile) vs cancel vs close.
Cancellation through KILL QUERY still instantiate new
ImpylaHS2Connection client.
3. Implement required missing methods in MinimalHS2Client.
4. Change MinimalHS2Client logging pattern to match with other clients.
Testing:
Pass test_cancellation.py and TestResultSpoolingCancellation in core
exploration mode. Also fix default_test_protocol to HS2 for these tests.
