lxqt-leave should detect remote sessions

[agaida]

Expected Behavior

On remote sessions the restart, hibernate, sleep, reboot and shutdown has to be disabled - or a complete other set of functionality should show up (Close Session (Logout) and Disconnect Session would be fine)

Current Behavior

Right now i can send my NAS to sleep or shut it down via lxqt-session, not so nice 😄

Possible Solution

Detect the running X - and react to it

Steps to Reproduce (for bugs)

1. Setup a xrdp-server or vnc-server
2. Connect to it
3. Hit shutdown or reboot in lxqt-leave
4. Be speechles and watch the remote machine :)

Context

This behaviour is fine, when i connect to a machine with teamviewer, anydesk or other remote tools that only transfer the client screen. It is not fine, if i open a virtual X on the machine and run LXQt on that virtual screen - my possible co-workers would hate me :D

System Information

Server: Modified CentOS (Rockstor)
Client: Siduction LXQt / Windows with a rdp client

Hmm - not really sure who should handle it - session or maybe policykit
