[lxd] Fixed commands for snap in lxd.py + added missing commands

The LXD plugin for sos had 2 main issues:

1. It was lacking in troubleshooting commands. For verifying cluster
quorum & health and for more information I have since added:
- lxc operation list
- lxc info
- lxc alias list
- lxc remote list
- lxc version
- lxc warning list
- lxc auth permission list
- lxc cluster list

All command use the local: remote.

2. The ‘snap’ section of the plugin was broken and did not capture
 much of anything except lxd.buginfo and the few lxc commands
 included only worked on debs. This has been changed to work on
 both the debian package and snap version of LXD.
