Description:
Improve the image metadata generation command

juju metadata generate-image was originally written
as a developer tool to aid simplestreams development.
It now is useful for setting up private clouds so has
been given a facelift to make it more user friendly.
The key feature is it will now use the current environment
to pick up most of what it needs, and the user just has to
supply the image id and architecture (if something different
to amd64 is required).
