This feature looks nice. No comments on the code itself. I have just one suggestion. I would call the command line parameter --debug and the environment variable CLOUDSCALE_DEBUG instead. The output this produces looks more like debugging output. As a user I would expect a --verbose option to output more information about the objects (eg. more detailed server list), not more information about the API requests done. Also with the Python logging formatting this looks more like debugging output.

Something a bit different not really specific to this PR: Is there a way to make certain CLI flags "global" so you don't have to define them for every command? Currently there is a lot of code duplication for all the flags that are the same for each command.

--debug would be indeed a appropriate option name.

Currently the only reason against "globaly" options is the cloudscale-cli version case, which takes no optioins at all. But at the end to have a non-functional options for cloudscale-cli version would not a big issue IMHO.

I would live with the non functional options on the version command (or make that an option itself --version) and make the common options global. But I leave this up to you and this is certainly nothing for this PR.

needs rebase and I would like to merge #4 first and working on top
