Add emacs interface to Docker

[Silex]

Hello,

Don't merge this yet

I created this PR as a motivation booster for me to finish my package https://github.com/Silex/docker.el :) And also to notice the world that this is a work in progress, and maybe get contributors.

I'm currently discussing with @emacs-pe wether the current docker.el package should be renamed to docker-tramp, see emacs-pe/docker-tramp.el#1.

Several things needs to be done:

• Get settled on the name of this package, maybe renaming it.
• Make a basic implementation for containers manipulation.
• Finish the various images tasks (right now only "rmi" works).

@purcell: I'll summon you when all these tasks are done for your little review magic :)

@purcell: I was reddited so this boosts me into making a basic implementation, just to notify you that you'd soon be able to do your quick review magic :)

docker.el requires docker-containers, which I don't see anywhere.

[Silex]

purcell: yeah it's in the containers branch, PEBKAC I'll merge it soon.

[Silex]

@purcell: okay, the basic functionnality is there now. Still a lot to improve but at least I think it's MELPA-able. Is the recipe good?

[purcell]

There's a recipe for a package called docker-api, but in the corresponding repo there isn't a docker-api.el or a docker-api-pkg.el. So that recipe isn't really valid. The other two recipes look fine.

[Silex]

Oops, right I forgot about this one. I'll remove it for now, it'll be an extra dependency later on but I can just change the docker-pkg.el for this and make a new PR for the dependency.

Thanks!

[Silex]

A'ight, if things looks ok I think you can merge.

[purcell]

Done, thanks!
