52785ab768 refactored required and
mutually exclusive module parameters and meanwhile dropped some
arguments required for our matrix_token_login module. The change
made sense for most of our modules, but the matrix_token_login as the
only one doesn't need token or password, but definitely needs a key.
Matrix Login can be performed with username/password or token from each module.
`matrix_[uia]_login` and `matrix_logout` is only needed, longer operations are wanted.
modules called with username/password will logout automatically.
The login/logout process is handled by the helper class (except matrix_uia_login).
