When we use `cfy cluster nodes remove`, we can update the relevant profiles.
all the profiles that are connected to that cluster can remove that
node from their cluster list
all the profiles for that node can remove their cluster list entirely
This will allow to `cfy use` that removed node again so that we can still
do ssh-related tasks on it (like teardown, or `cfy dev`).
(This `cfy use` will however require `--skip-credentials-validation`
