remove docker from devstack

with I1c9bea2fdeebc4199c4f7d8fca4580a6fb7fed5b nova removed
docker from it's driver tree.

We shouldn't have driver support inside of devstack that's not
part of upstream projects (this has been a line we've been
pretty clear on with Neutron drivers in the past).

Remove docker driver accordingly.

This is a recent change (Oct 2013) from the previous behaviour of
automatically creating a ``stack`` user. Automatically creating
user accounts is not the right response to running as root, so
that bit is now an explicit step using ``tools/create-stack-user.sh``.

Run that (as root!) or just check it out to see what DevStack's

# DevStack on Docker
Using Docker as Nova's hypervisor requries two steps:
* Configure DevStack by adding the following to `localrc`::
VIRT_DRIVER=docker
* Download and install the Docker service and images::
tools/docker/install_docker.sh
After this, `stack.sh` should run as normal.
