Include 'run' argument to docker_container :commit about docker

[bflad]

Great idea. I was thinking of adding this from the get go, obviously I should've just done it. I'm thinking maybe runspec as the name for the attribute? Have you tried using the new actions? Do they work in your environment? I was implementing features ahead of my usage/testing.

I would suggest that you simply name it 'run' to simplify 'translation' between the docker CLI and cookbooks, though I guess that may be a moot point since other attributes already differ some what. Just my opinion. :)

I was happy to find the new support for importing from tarballs, though I may have stumbled across a bug that I'll have to investigate more tomorrow (attempting to import two in a row resulted in one or both succeeding depending on the ordering, so I don't know if it's just on my end yet).

Released in 0.25.1. Enjoy! If you had time to investigate the possible bug, please submit a new issue and I'll take a look.
