Feat: Some server related API features

[jibon57]

I think most of the these API methods should be cover here: https://github.com/8xFF/atm0s-media-server-console
But I'm still listing:

• Rooms List
• Get Room Information (including peers + tracks)
• Peers List
• Get Peer Information (including tracks)
• End/Delete room, when we use this API method during that time room will be clean up + peers leave + tracks cleanup
• Remove peer
• Update metadata/peerExtraData (when update all the client should receive notification by event with new updated data)
• Send data message, sometime application need to receive various information & having an API will be helpful to broadcast information among all the peers.
