MXS-2219 Update datastructures instead of recreating them

Browse Source 
The node infos of the Clustrix servers are now kept around and
and updated based upon changing conditions instead of regularly
being re-created.

Further, the server is now looked up by name only right after
having been created (and that only due to runtime_create_server()
currently being used).

The state of the dynamically created server is now updated directly
as a result of the health-check ping, while the state of the bootstrap
servers is updated during the tick()-call according to the monitor
"protocol".
