create a docker container out of a setup chroot

[msmeissn]

it would be useful if

osc build

would have an option to generate a docker container to capture the build environment, for transfering and later usage to rebuild a package.

osc build --vm-type=docker is not what you look for?

But actually, for replaying build enviroments of maintained projets we have the _buildenv files. You can use them also as source and build in what ever environment you want (ideally KVM to have the same as for the shipped binary).
