This is the last thing using Chef, which adds a lot of time to the time it
takes to fully provision the buildserver. This slows down development on
the things we are actually using, like running all builds on
jenkins.debian.net.

This forces the release channel and version of chef-solo to install on the
guest VM. I was getting really massive, odd stacktraces without specifying
this, and chef is only used for Kivy now anyway.
The technique where /var/cache/apt is mounted as a shared folder conflicts
with vagrant-cachier's workings. Therefore, ignore vagrant-cachier if the
user selects ./makebuildserver's custom apt cache. The shared folder way
has the advantage for CI builds of storing the cache outside of
VAGRANT_HOME, which is set to be in the git project. That gets wiped by
`git clean -fdx` on each CI build.
Vagrantfile is now committed and not changed between configurations. It is
configed by translating the python config file's dict to a YAML file, which
Vagrantfile now loads and uses. This makes it a lot easier for vagrant
users and python programmers to understand, and hopefully makes it easier
to maintain and test with.
