Remove deprecated references to oslo-incubator
Purge references to modules which have been deprecated by various oslo libraries. Requires changes to use oslo.utils and oslo.concurrency, which are added to the requirements, syncing with the latest in global requirements so we can also move to the un-namespaced oslo package names.
