Need to create systemd unit to tell docker to wait for storage

[cgwalters]

Normally, LVM devices are probed pretty early, but it can happen that storage devices are slow to start. I have a box with ~ 20 TB across 20 disks, and sometimes on boot not all of them have spun up by the time docker starts.

We'll need to tweak d-s-s to generate a systemd drop-in in /etc/systemd/system/docker.service.d with Before=dev-mapper-docker--meta.device dev-mapper-docker--data.device

Should we make this part of the core package?
