Gael Chamoulaud 08533b45c3 Use dynamic argument_spec from documentation
This change modifies the argument_spec making it so we load the options
key from the documentation constant. This will reduce the code we have
to maintain and ensure our documentation is always in sync with the
module capabilities.
