Add Fedora support

[brauner]

This came up on the lxc-users mailing list. We should add Fedora support or encourage the community to work on Fedora support. :)

I am intrested on adding Fedora support.
How diffucult is to create a tool that can "containerize" any X86-64 physical machine ?

[monstermunchkin]

I can take care of this.

@monstermunchkin I can try to implement this, I can't be much different from the one from CentOS :)

Our experience with the old style templates (lxc-centos vs lxc-fedora) is that it's unfortunately very very different as centos/rhel/oracle can be bootstrapped with an old minimal yum while fedora doesn't and so required us downloading a big pre-built image (squashfs) and then using that as the base.

In this case, I believe @monstermunchkin found some pre-existing Fedora images (container minimal base) which we can teach distrobuilder to download and use as a supportable working base on top of which we can add/remove packages.

So that'd be a download style source for Fedora combined with a dnf package manager, shouldn't be very difficult but will end up being pretty different from centos.
