We install projects if they are python in the sphinx jobs because autodoc needs to be able to import the package. Also, for pbr projects, many projects have links to ChangeLog in the docs, which is generated by pbr on install and sdist. Installing with pip install --no-deps does not cause the ChangeLog to be generated, so trigger it via an sdist build first. Change-Id: I4528cc7f322d1fc753eb5bc259f70c47ee9d1d80
