Container or cvmfs for reana-client

Hi,

it will be great if the reana-client can be accessible via container or cvmfs. My case in point:
I want to run the client as part of my gitlab-ci. I am thinking that the job in the gitlab-ci is allowed to fail if the user pushing/making a merge request does not have the correct secrets or does not have reana user, but it can be run by the other users. 

thanks
