Application can depend on several overlayfs mount points. Provide a
systemd unit application can depend on to make sure all overlays are
mounted before it is started to avoid any race conditions

It's often desired in Embedded System design to have a read-only rootfs.
But a lot of different applications might want to have a read-write access
to some parts of a filesystem. It can be especially useful when your update
mechanism overwrites the whole rootfs, but you want your application data
to be preserved between updates. This class provides a way to achieve that
by means of overlayfs and at the same time keeping the base rootfs read-only.
