Move rsnapshot functionality to supplemental/rsnapshot

Both postgres and mysql require the rsnapshot role to run first!

-# If enabled, rsnapshot will write a lockfile to prevent two instances

-# When sync_first is enabled, it changes the default behaviour of rsnapshot.
-# Normally, when rsnapshot is called with its lowest interval
-# (i.e.: "rsnapshot alpha"), it will sync files AND rotate the lowest
-# intervals. With sync_first enabled, "rsnapshot sync" handles the file sync,
-# and all interval calls simply rotate files. See the man page for more

-#
-#sync_first	0

-# If enabled, rsnapshot will move the oldest directory for each interval

-# Number of rsync re-tries. If you experience any network problems or
