Migrates master to use direct upstream

Migrates master to use direct upstream

We now move master to deploy from upstream.  That means we do not need
to build undercloud/overcloud images anymore.

Changes-Include:
 - Remove bash build scripts as we do not need to build anything
   other than the python package anymore
 - Remove building images or iso from build.py
 - Remove building of images and iso from Makefile
 - Rename/refactor deploy settings files for nosdn and odl.  The new
   convention is that the typical scenario names we use will deploy
   master.  We also support n-1 OS, so in that case we use the branch
   name for the "feature" in the scenario name: os-odl-queens-noha.
 - Tacker/Congress are disabled in settings files until we fix that with
   upstream.  Containers are now enabled by default.
 - Disable TLS for undercloud (was changed upstream to default enabled)
 - Fix environments docker directory for master THT (was changed upstream)
 - Includes fix for LP#1768901
 - Includes workaround for LP#1770692
 - Moves to docker.io for container images as it is more stable and
   should contain the same images
 - Removes the term 'common' from apex packaging for referencing the
   Python Apex package
