IMPALA-13912: Use SHARED_CLUSTER_ARGS in more custom cluster tests
In addition to IMPALA-13503 which allowed having the single cluster
running for the entire test class, this attempts to minimize restarting
between the existing tests without modifying any of their code.
This changeset saves the command line with which
'start-impala-cluster.py' has been run and skips the restarting if the
command line is the same for the next test.
Some tests however do require restart due to the specific metrics being
tested. Such tests are defined with the 'force_restart' flag within the
'with_args' decorator. NOTE: there might be more tests like that
revealed after running the tests in different order resulting in test
failures.
Experimentally, this results in ~150 fewer restarts, mostly coming from
restarts between tests. As for restarts between different variants of
the same test, most of the cluster tests are restricted to single
variant, although multi-variant tests occur occasionally.
