fix(contrib): check that coreos/user-data has a discovery_url set
fix(vagrant): disable vagrant cachier if present

Vagrant cachier trys to use vboxfs mounts if it is installed. Disable it if present.
fix(readthedocs): install CLI requirements explicitly

Readthedocs.org began failing to generate our Python code autodocs
recently. Purging the build environment (use https://readthedocs.org/wipe/deis/latest/)
did not help. Their logs indicate Sphinx is confused by a version of
the urllib3 library that happens to be installed in the system python.
This packaging error was fixed in urllib3 1.8.2, see https://pypi.python.org/pypi/urllib3.
This adds the client's requirements explicitly to the docs_requirements.txt
so that this broken version of urllib3 isn't used.

This is also fixed by requests 2.3.0, but pinning urllib3 seemed like
a safer fix.
feat(docker registry): add Vagrantfile for Docker registry

Adds a contrib/docker-registry directory with a Vagrantfile that
configures and starts a VM with the Docker registry service.

fix(controller) disable django admin URL

If you accidentally create an object that requires an external library
such as the Release object, no docker image will be pushed to the registry,
which is unintentional. This disables the django admin URL such that you can't
shoot yourself in the :shoe:.
docs(pip install): add --upgrade to `pip install deis`

This flag is safe to use as a default, and would avoid the problem
reported on IRC where an existing deis client stays out-of-date if
you follow our instructions exactly.

chore(*): rely on etcdctl in deis/base

As of deis/base#4, etcdctl v0.4.2 includes the --no-sync option.
We no longer need to install an etcdctl branch just to get this
option.
fix(logger): turn off verbose untar'ing

untar'ing go's tarball dumps out a lot of unneeded lines. This
cleans up the build process a bit.
