Title: [AS7-5598] relax cluster-connection constraints

AS7-5107 added a constraint to the cluster-connection to have
either a static-connectors or a discovery-group-ref defined.

However there is 1 case where it is valid to define a cluster-connection
without static-connectors or discovery-group-ref: when it is part of a
cluster and it accepts connections from other nodes but does not connect
to any other node.
This is a edge case but a valid one.

This commits relaxes the constraints and accepts a cluster-connection
without one of these attributes
