MXS-1446: Store more detailed event information

Browse Source 
The timestamp of the last change from passive to active is now
tracked. This, with the timestamps of the last master_down and master_up
events, allows detection of cases when MaxScale was failed over but the
failover was not done.

Currently, only a warning is logged if no new master has appeared within
90 seconds of a master_down event and MaxScale was set to active from
passive.

The last event and when the event was triggered is now shown for all
servers. The latest change from passive to active is also shown.
