Keep track of SSH Keys used
Every time an SSH Key is used, we should let minarca-server know about when it was used and keep track of the last used date. Then this value may be displayed in the UI to help the user delete obsolete SSH Keys.
Technicalities: minarca-shell could simply call the web service in background for each successful connection. This http entry point, should allow unauthenticated request to be submitted with a TOKEN key. Let see what we can do about this.
