MXS-1848 Use MXS_SPECIFIC_MONITOR type in monitor APIs

Browse Source 
Now, all monitor functions but startMonitor takes a
MXS_SPECIFIC_MONITOR instead of MXS_MONITOR. That is, startMonitor
is now like a static factory member returning a new specific
monitor instance and the other functions are like member functions
of that instance.
