this series improves the systemd integration of LXC containers by:
- ensuring PVE LXC container units don't have a (transitive) conflict with shutdown.target, thus preventing races between systemd- and pve-ha-lrm/pve-guest initiated stopping of containers
- reworking the stop/reboot handling to reduce log spam of failed redundant lxc-stop calls, by only calling lxc-stop in our wrapper if the unit has not already successfully exited
- installing snippets/unit to the correct location in /lib/systemd/system

changes since v4:
- copy and rework lxc-pve-reboot-trigger as pve-container-stop-wrapper
- use pve-container-stop-wrapper as ExecStop in pve-container@, instead of lxc-stop as ExecStop and lxc-pve-reboot-trigger as ExecStopPost

tested the following scenarios:
- shutdown and reboot from within
- shutdown via pct stop/API
- shutdown and restart via systemctl stop/restart

Fabian Gr├╝nbichler (4):
  install lxc@ snippets to correct location
  add new pve-container units
  switch to pve-container@ unit
  build: mark lxc at .service.d for future removal
