 Description   

Introduce a cluster concept for specifying the servers of services and monitors. So, instead of

[Server1]
 
type=server
 
...
 
[Service1]
 
type=service
 
servers=Server1,Server2,Server3,...
 
...
 
[Monitor1]
 
type=monitor
 
module=mariadbmon
 
servers=Server1,Server2,Server3,...
 
...

you would be able to express it like

[Cluster1]
 
type=cluster
 
monitor=mariadbmon
 
servers=Server1,Server2,Server3,...
 
...
 
[Service1]
 
type=service
 
cluster=Cluster1
 
...

With this change it is possible to introduce monitors that autonomously and dynamically at runtime provide the list of servers. For instance, a monitor for Clustrix.
