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.
