When logged into a registry that supports token-based authentication, tell the
server to end this token's session. This will invalidate the token everywhere
you're using it, not just for the current environment.
When logged into a legacy registry that uses username and password authentication, this will
clear the credentials in your user configuration. In this case, it will only affect
the current environment.
If --scope is provided, this will find the credentials for the registry
connected to that scope, if set.
