Add tests for the scheduled failover.

Browse Source 
The actual amount of time to establish the master and the replication
after the scheduled failover seems sufficient (15 seconds with the
failover in 10 seconds), but occasionally leads to test failures.
This is unlikely the test issue and should be investigated inside
the patroni.
