Some of the tests waited for excessively long periods of time for changes
to propagate. With a one second monitor interval, a sleep of around five
seconds should be plenty enough for all monitor related changes to be
propagated to all systems.
The test restarts MaxScale while all backends are blocked. This will cause
MaxScale to wait until all connections to all servers time out which can
take a while.
Added a separate config for the test and lowered the timeouts. Also
inreased test timeouts.
