IMPALA-13682: Implement missing capabilities in ImpylaHS2Client

This patch implements 'wait_for_finished_timeout',
'wait_for_admission_control', and 'get_admission_result' for
ImpylaHS2Client.

This patch also changes the behavior of ImpylaHS2Client to produce
several extra cursors aside from self.__cursor for 'execute' call that
supplies user argument and each 'execuse_async' to make issuing multiple
concurrent queries possible. Note that each HS2 cursor opens its own HS2
Session. Therefore, this patch breaks the assumption that an
ImpylaHS2Client is always under a single HS2 Session (see HIVE-11402 and
HIVE-14247 on why concurrent query with shared HS2 Session is
problematic). However, they do share the same query options stored at
self.__query_options. In practice, most Impala tests do not care about
running concurrent queries under a single HS2 session but only require
them to use the same query options.

The following additions are new for both BeeswaxClient and
ImpylaHS2Client:
- Add methods 'get_test_protocol', 'get_host_port', and 'log_client' for
  convenience.
- Implement consistent query state mapping and checking through several
  accessor methods.
- Add methods 'wait_for_impala_state' and 'wait_for_any_impala_state'
  that use 'get_impala_exec_state' method internally.
- Add 'fetch_profile_after_close' parameter to 'close_query' method. If
  True, 'close_query' will return the query profile after closing the
  query.
- Add 'discard_results' parameter for 'fetch' method. This can save time
  parsing results if the test does not care about the result.
- Always lower the query option name in 'set_configuration_option'.

Added helper methods in ImpalaTestSuite and ImpaladService to create a
new client from the test vector. Reuse existing op_handle_to_query_id
and add new session_handle_to_query_id to parse HS2
TOperationHandle.operationId.guid and TSessionHandle.sessionId.guid
respectively.

To show that ImpylaHS2Client is on par with BeeswaxClient, this patch
refactors test_admission_controller.py to test using HS2 protocol by
default. Test that does raw HS2 RPC (require capabilities from
HS2TestSuite) is separated out into a new TestAdmissionControllerRawHS2
class and stays using beeswax protocol. by default. All other tests
create a new test client based on the given test vector, rather than
using ImpalaTestSuite.client (a BeeswaxClient) directly.
QUERY_WITH_UNPARTITIONED_FRAGMENTS is rewritten to use the full table
name. This allows us to remove all ImpalaTestSuite.change_database
calls.

Testing:
- Pass exhaustive tests.
