39df829384 Don't kick out super-users when performing rejoin 
When rejoining a server, preventing writes is not as essential as in switchover.

a60bd37610 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.

d0e6921604 Improve switchover undo when new master fails 
Now the monitor properly restores the old master by running promotion code on it.
Also, binlog is disabled when enabling server events.

650230455a MXS-2169 Allow unsafe failover when 'enforce_simple_topology' is on 
If gtid of master is unknown (as is typical when master is down when MaxScale
starts) the domain id is guessed from the slaves instead. This is usually
safe.

f8a22d0ac0 MXS-2344 Add setting for enabling SSL for replication 
If the monitor setting "replication_master_ssl" is set to on, any CHANGE MASTER TO-command
will have MASTER_SSL=1. If set to off or unset, MASTER_SSL is left unchanged to match existing
behaviour.

4fd4b726a1 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.

90e6ff078a Divide ClusterOperation to two types 
The main class was getting unwieldly and too general. Dividing the fields
helps adding support for other operation types.

This commit leaves most data duplicated, later commits clean up the affected code.

2d61b78439 Fix low disk space maintenance 
The setting didn't work because the code updated a status flag which
would be overwritten before being read. Also, promotion code now checks
that the server is not in maintenance.

0c203fa02d Don't redirect duplicate connections 
The redirection method checks if a slave connection to the redirection
target already exists. If so, the connection is not modified. Also, failover
better detects duplicate connections during promotion.

c10fab977d Cleanup slave connection copy & merge 
The two cases are now separated. In switchover, the promotion and
demotion targets can swap connections between each other without worry.
In failover, the two connection lists must be merged semi-intelligently.

The slave connections of the two servers are now saved to the operation
descriptor object at the start of the operation. This allows slave status
updating during the operation.
