PT40715849: Adding 2 or more mongo service at same time doesn't work

- do not attempt to link running mongo servers, only start/stop them in services pages
- built specialized mongo db page (Server > Databeses) that show state of each running server. Admin could remove/add servers to replication set and see server state
- global warning added in case replica set not properly configured

Fixed iptables generation error when call no call rate limit
