[Container-tools] Including docker images in ADB Vagrant box

[Lalatendu Mohanty]

Hi,

One of the thing we want to do with ADB (Atomic Developer Bundle) is to 
pre-load the vagrant box with some docker images (e.g. OpenShift docker 
image).

I have spent some time on this and I found this to be more tricky then I 
thought. Here are the details.

* We use koji to build the Vagrant box from a kickstart file and koji 
does not have access to internet for some valid reasons. Hence we cant 
do "docker pull" during the build process as it does not have access to 
internet.

* So as a workaround we thought of packaging the docker images in a RPM 
and use the RPM in the kickstart file to bake it in to the Vagrant box.

Here is the poc git repo for that :

Comments/suggestion are welcome.

Let me know if you have a better idea to build Vagrant boxes with docker 
images pre-loaded in koji.

Thanks,
Lala
