In the dependent change, the docker roles will add sibling packages to
the .zuul-siblings directory of the checked-out source.
Refactor the "assemble" script to handle this. Essentially we build
the wheel for "." and then iterate over ZUUL_SIBLINGS subdirectories
(set in a --build-arg by the role in dependent change) to also build
the sibling packages. Note we concatenate the bindep.txt files, so
that we end up with the complete package list required by the main
code and its dependencies.
"install-from-bindep" now installs all the wheels, using --force to
make sure we re-install the speculatively built packages.
This means that a single Dockerfile works under Zuul when
ZUUL_SIBLINGS is set, pointing to Zuul's checkouts; but it also works
stand-alone -- in this case ZUUL_SIBLINGS is empty and we just install
from upstream as usual.

There are cases when an issue has been fixed upstream in a
dependency but not yet released and it is desirable to install
that version in a built image. pbr does not support such urls
in requirements files because releasing software that depends
on unreleased software is quite dangerous.
Update assemble and install-from-bindep to install -r requirements.txt
before installing the actual software so that image builds with
such requirements lines will work.

This is a builder image intended to make it easy to build
images for projects that use pbr and bindep.
Also, build a python-base image for use with python-builder
pbrx installed dumb-init in a base image and used it as an
entrypoint for the image. This is a good pattern that we should
continue. Make a python-base image that can be used in the FROM
line of consuming final images.
