MXS-2546 Separate slave connection settings to its own class
...
The settings are different from the other fields in that they should not change
on their own. Most manipulation functions only require the settings.
Also takes into use a class for host and port data.

MXS-2367 Print slave connection errors when replication fails
...
The slave connection I/O-tread stays running if replication credentials are
wrong when connecting to master. This causes a switchover/failover timeout.
When this happens, print the error in the slave connection status as this
clarifies the problem to the user.

If gtid of master is unknown (as is typical when master is down when MaxScale

MXS-2325 Only enable events that were enabled on the master
...
The monitor now continuously updates a list of enabled server events. When
promoting a new master in failover/switchover, only events that were enabled
on the previous master are enabled on the new. This avoids enabling events
that may have been disabled on the master yet stayed in the SLAVESIDE_DISABLED-
state on the slave.
In the case of reset-replication command, events on the new master are only
enabled if the monitor had a master when the command was launched. Otherwise
all events remain disabled.
