Currently we cannot import source archives with names different
than expected by hardcoded line in Dockerfiles. This worked well
for Openstack services' tarballs where we expected SERVICE-* root
folder after extraction or kanaka-noVNC for nova-novncproxy docker.
The latter fails if one tries to clone or get tarball under other
names. This fix allows any archive (tar,tgz,zip) or repo name to be
imported into dockerfile.

This creates and moves the dependencies for Ubuntu into a common
openstack-base container. This commit shows dramatically smaller
sizes for all non-openstack containers. The Openstack container remain
the same size.

We can, and should, figure out the filename dynamically rather than
hardcode that value in build.ini since it is not actually a
configurable paramater.
