Boaz Leskes c89fdd938e ZenDiscovery - only validate min_master_nodes values if local node is master (#23915) ...

The purpose of this validation is to make sure that the master doesn't step down
due to a change in master nodes, which also means that there is no way to revert
an accidental change. Since we validate using the current cluster state (and
not the one from which the settings come from) we have to be careful and only
validate if the local node is already a master. Doing so all the time causes
subtle issues. For example, a node that joins a cluster has no nodes in its
current cluster state. When it receives a cluster state from the master with
a dynamic minimum master nodes setting int it, we must make sure we don't reject it.

Closes #23695
