Add initial commit of new media management docker stack

Includes transmission, gluetun, sonarr, radarr stacks
Includes framework for adding plex, tautulli, prowlarr, overseerr, requestrr, and trash guides sync stacks
Includes port-watcher docker container that monitors gluetun port forwarding file and sets transmission peer_port automatically
