Tracking how many times the monitor has performed its monitoring allows
the test framework to consistently wait for an event instead of waiting
for a hard-coded time period. The MaxCtrl `api get` command can be used to
easily extract the numeric value.
The monitor performs simple monitoring of a group replication cluster. It
expects no extra parameters in addition to the common monitor parameters
and will only set master and slave status bits on the servers. It is a
part of the experimental package as it is a very experimental module.
Further improvements would be to add the usage of the synced state.
