This ticket was already reviewed and ack. But later I realized I had to
revisit it for the following changes:
- py.test fixture 'topology' to handle different conditions
(instance/backup exists or not and is started or not)
- finalyser.py to remove all created instances (final module
called by py.test)
- stop the instance after the test suite (test_ticketxyz_final)
- ability to run ticket47490 test case with python script (no
use of py.test) -> run_isolated( )
Test case routine 'test_ticket47560(topology)' did not change compare to
the previous review.
