Added metadata for new release feature/roxy-docker
json-edit: Allow using stdin/stdout as json input

With this change we can use json-edit (instead of sed) inside the various
smoketest/modify-json scripts that smoketest calls.
smoketest: Add (very simple) distro detection

This should be enough to avoid doing the same test in the barclamps'
smoke testing scripts.
smoketest: Provide an install_package function

To handle the different package installation commands on the various
supported distros.
install-chef-suse: install smoketest tools when using --from-git
Add support for git tracked metadata.

This is intended to let other people test drive using git tracked
metadata.  Support is not complete -- the dev tool still needs to be
updated to pull in and track the metadata tracking repo like it tracks
the barclamps, and support needs to be added to ./dev setup to start
pulling in the metadata tracking repo.
Allow ipv6 on networks.
First part of openSUSE 13.1 support
