Remove multi-master monitor
...
Was deprecated in 2.3. Similar features are in MariaDB-Monitor.
One system test was modified to use MariaDB-Monitor instead. Some parts
of the test are disabled for now to make it pass.

MXS-2275 Check for softfailed nodes
...
When checking the node info, also include information about wheter
a node is being SOFTFAILed. If it is, turn on the `Being Drained`
bit.
A node is SOFTFAILed with the intention of removing it, so better
not to create new connections to it as they later would be broken
when the node is actually taken down.

MXS-2275 Implement [un]softfailing
...
It is now possible to [un]softfail a Clustrix node via MaxScale
using a Clustrix monitor module command.
In case a node is successfully softfailed, the `Being Drained` bit
will automatically turned on. Similarly, if a node is successfully
unsoftfailed, the `Being Drained` bit will be cleared.

MXS-1937 Cleanup event handling
...
Event handling is now enabled by default. If the monitor cannot query the EVENTS-
table (most likely because of missing credentials), print an error suggesting to
turn the feature off.
When disabling events on a rejoining standalone server (likely a former master),
disable binlog event recording for the session. This prevents the ALTER EVENT
queries from generating binlog events.
Also added documentation and combined similar parts in the code.
