Rclone v1.40 for Plex/Sonarr/Radarr Read/Write

This small guide should help you get setup with rclone v1.40 to read/write directly to a cache mount and have Plex get notified of new tv/movies that get added to the mount by Radarr/Sonarr

Assumptions

1. You're using rclone v1.40
2. You're using Radarr & Sonarr
3. If you're using docker for plex/sonarr/radrr, you must ensure the volumes attached to the containers are all the same path, i.e.: /mnt/user/media:/media for all 3. If not, the auto-scan will likely not work properly.
