Commit I9272f71e0e68268ad9f558ddd1e1183e3ea69806 fixed a few deprecation warnings due to properties being renamed in oslo context, but there were a few other name changes as well. This updates domain_id, project_domain_id, and user_domain_id and gets rid of ~130 DeprecationWarning messages from our unit test runs. Change-Id: Ic7e8e6bc5c68e73a2c26c3105885e5c6ea06a4a8
