First shot at stonith per node table
webui: Disable no-quorum-policy option when there are not enough nodes

If the cluster has less than two nodes, then the no-quorum-policy must
be forced to "ignore" and we also disable the select widget for it.

Since we know that there will always be a node with the founder role,
the condition is really on the number of non-founder nodes.
