It is necessary to forbid adding MongoDB nodes if there are deployed nodes already

[Alexander Kislitsky]

During the deployment MongoDB nodes are configured as primary-secondary servers.

In case of adding MongoDB nodes into current configuration we must reconfigure OpenStack and redeploy MongoDB nodes. Reconfiguration and redeployment cause data loosing.

So now we should forbid adding MongoDB nodes if there are already deployed nodes in UI.
