This change is needed for clarity. We have a kolla-ansible script.
We have a kolla-mesos repo. We plan to have a kolla-ansible repo.
Already we have had far too much confusion about whether we are
talking about the container or the project. Naming this kolla-toolbox
eliminates all of that confusion and its probably a bit more accurate
of a name too.

This currently deploys the core services for a working Swift which are
account/container/object/proxy.

I've included some basic docs in docs/swift-related.rst, which gives
usage instructions and more context on this patch. These are really to
give an overview of the state of Swift in Kolla as of now, so unless
there's some major inaccuracy there please don't nitpick it.
