Add support for path based registry in login/logout
Browse files Browse the repository at this point in the history 
We now add a new configuration option to opt-in for path based registry
authentication in containers-auth.json. This affects login and logout,
which means if the option is enabled we can now use
`my-registry.local/path/to/image` to save or remove the credentials from
the auth.json.

If the option is enabled, then we enforce a stricter validation of the
input. For example it is not allowed input `http[s]://` prefixed keys.
