As of now, in most of the test cases, uuidsentinel is used for generating a UUID except at some places where uuid4() is used. In order to maintain consistency, we propose to use uuidsentinel module for generating UUIDs throughout the test cases. There are some cases where unique UUIDs are required. For such cases, generate_uuid() from oslo_utils.uuidutils is used. Change-Id: Ifaee2f79fc33d189751c4e3f405b579dd8d89784
