The oslo team is recommending everyone to switch to the non-namespaced versions of libraries. Updating the hacking rule to include a check to prevent oslo.* import from creeping back in. This commit includes: - using oslo_utils instead of oslo.utils - using oslo_serialization instead of oslo.serialization - using oslo_db instead of oslo.db - using oslo_i18n instead of oslo.i18n - using oslo_middleware instead of oslo.middleware - using oslo_config instead of oslo.config - using oslo_messaging instead of "from oslo import messaging" - using oslo_vmware instead of oslo.vmware Change-Id: I3e2eb147b321ce3e928817b62abcb7d023c5f13f
