Mount sync

Syncronize some “mounted” filesystems with the local one. Typically used for EFS/NFS mounts on autoscale clusters. It will:

perform an initial rsync using a cloud-init script
use Unison to perform regular checks (mostly to catch edge-cases where an instance would be spinned up during the middle of a deployment)
