cephadm: init config and keyring with None

and we should not assume that both `config` and `keying` are specified
when calling this method. because, for instance, `create_daemon_dirs()`
does handle the case where `config` and/or `keyring` is not specified.

this is a follow-up fix of 245d6a5cec9cc0f299613b8cc0415e494a4c3ac5
