Make identity v2 roles_client use **kwargs

As we discussed on
http://lists.openstack.org/pipermail/openstack-dev/2015-July/068864.html
All http POST/PUT methods need to contain **kwargs as their arguments.
This patch makes identity v2 roles_client use **kwargs.

Also rename some method to match the consistency and later those
can match with v3 clients methods naming and we can remove many wrapper
method exist currently to call v2 and v3 methods.

Partially implements blueprint consistent-service-method-names
