support for keystone v3 api - keystone::endpoint

This patch implements these parts of the blueprint:

1) Adds support for domains to keystone::endpoint
Users of this resource may specify a different domain for both the user
and the tenant/project, or may specify the default domain which will apply
to both user and tenant.
