Hey Thiago,

Thanks for your feedback.

I just wanted to provide some feedback on why this change was made. In V2,
the image location is a resource and you can have multiple locations per
image. In order to allow you to add locations, we had to add the
`location-add` subcommand. Then the `--location` argument was removed so
that we would have 1 way to do things rather than 2.

I do understand where your frustration comes from and I'd also prefer a
single command rather than 2 (or 3) but in this case consistency with the
API was favored over having 2 ways of doing things in the CLI.

Thanks again. I certainly hope glanceclient v2 is not causing you more
frustrations.
