IMPALA-12848: Fixed flaky test test_catalogd_ha_failover

TestExtDataSources::test_catalogd_ha_failover failed to delete data
source object after catalog service failed over to standby catalogd.
Log messages showed that coordinator tried to submit the DDL request
to original active catalogd since it did not receive failover
notification from statestored yet.

To fix the flaky test, wait until coordinator receive failover
notification from statestored before executing DDL request to drop
data source.

Testing:
 - Looped to run the test for more than hundred times without failure.
