Unable to specify domain_id when registering an identity provider

[Lance Bragstad]

Keystone server supports associating a domain when registering an identity provider [0]. The client doesn't support passing this information to the server, yet.

We should update the client so that operators can specify a domain ID for an identity provider. If a domain ID isn't specified in the request to register an identity provider, keystone will automatically generate one.

Seems the domain_id can be contained in **kwargs: https://github.com/openstack/python-keystoneclient/blob/master/keystoneclient/v3/contrib/federation/identity_providers.py#L41

openstack client has supported it already:
https://github.com/openstack/python-openstackclient/blob/master/openstackclient/identity/v3/identity_provider.py#L102

The docstring should be updated https://github.com/openstack/python-keystoneclient/blob/master/keystoneclient/v3/contrib/federation/identity_providers.py#L48-L49
