Use the new "edge" and "stable" repositories

[vide]

Since Docker Inc has changed its release cycle, they now have an "edge" channel, with monthly releases, and a "stable" channel, with releases every 4 months. Right now the repo configured by this module, at least, in CentOS, only configure the "edge" channel (I think because it's a remap of the old unique distribution channel). Here are the instructions on how to install them.

Are you going to accept a PR on this topic? I don't want to spend time on it if it's going to be ignored. Thanks!
