IMPALA-7790: Skip some Kudu tests if use_hybrid_clock=false
Since IMPALA-6812, we've run many of our tests against Kudu at the
READ_AT_SNAPSHOT scan level, which ensures consistent results. This
scan level is only supported if Kudu is run with the flag
--use_hybrid_clock=true (which is the default).
This patch uses the Kudu master webui to detect when use_hybrid_clock
is false and skips these tests.
Follow up work will address allowing these tests to run regardless of
the value of the flag.
Testing:
- Ran a full exhaustive build with use_hybrid_clock=false set in the
minicluster.

> Since IMPALA-6812, we've run many of our tests against Kudu at the
> READ_AT_SNAPSHOT scan level, which ensures consistent results. This scan
> level is only supported if Kudu is run with the flag --use_hybrid_clock=true
> (which is the default).
> This hasn't generally been a problem in the past, as we've primarily run
> Impala's functional tests against the minicluster, where Kudu is configured
> correctly, but there's been some effort around running these tests against
> real clusters, in which case --use_hybrid_clock=false may be set.
> We should at a minimum recognize this situation and skip the tests.
