Our CI infrastructure and developers have different requirements,
but really the overlap is almost complete and it's a shame that
we require developers to perform manual steps before we can use
our tools.
Flavors are a very simple and effective way to deal with the
issue: we'll be able to configure guests differently based on
whether they will be used for CI or development.
The default flavor is developer, which doesn't require the vault
password and as such can be used by anyone out of the box: the
Jenkins setup is skipped in this case.
