[WIP] Bring in onmetal-fast-docker for OnMetalIO

This brings in some of the pieces from https://github.com/jayofdoom/onmetal-fast-docker, to setup the LSI Nytro WarpDrives and put `/var/lib/docker` in them. I committed as @jayofdoom to give him credit for the initial files. I'll be adding in configuration sometime later.

We probably want to make this generic enough that if you want it to only setup the cards (but not mount docker there), you can do that.

One piece that will need to be added to the produced config is:

```
coreos:
  units:
    - name: systemd-sysctl.service
      command: restart
```
