MXS-2219 Dynamically create Clustrix servers
...
MaxScale server objects are now created for all Clustrix nodes.
Currently the name is "Clustrix-Server-N" where N is the number
of the node.
The server is created using runtime_create_server() that has been
modified so that it optionally will not persist the created server.
That is probably just a temporary solution as a monitor should not
need to include .../core/internal-stuff.

MXS-2219 Add health check threshold

MXS-2219 Perform cluster monitoring as well
...
Now the monitor
- will frequently ping the health port of each server
- less frequently check from system.membership the actual
number of available nodes
and act accordingly.
Currently, the updated servers are the ones listed in the conf
file. Subsequently this will be changed so that the servers listed
in the configuration file are only used for bootstrapping the monitor
and server objects are then created dynamically according to what is
found in the cluster.

MXS-2163 Make MariaDBMon recognize Clustrix
...
To allow MariaDBMon to be used with Clustrix we need to handle
Clustrix separately as its apparent version is 5.0.45, which is
lower than what MariaDBMon supports. Further, we must ensure that
Clustrix does not query the slave status as there are no slaves
in the M/S sense in a Clustrix cluster.
NOTE: Once there is a specific Clustrix monitor, this code should
be removed.

MXS-2175: Fix available_when_donor
...
If a Galera cluster drops down to a single node, the last node would not
be considered valid. During the failure of the second to last node, the
master would also temporarily lose the master status.
The behavior was changed to always keep the cluster UUID until the cluster
size drops down to zero. This guarantees that the same cluster is used as
long as possible.
