Feature request: Show infrastructure information

[Megamuch]

liKe #228 It would be great to have a summary overview of the Sip RTP and FS ip's, both public and private. There are many moving parts and a live overview about different ip's, host names, from the different parts could be really useful

This should be a read-only view in the settings panel for an admin user, probably a new tab labeled "Infrastructure"
