oslosphinx has been unmaintained for multiple cycles and we shouldn't
be using it anymore.
Some minor changes to the specs were necessary because the newer
sphinx introduced some warnings that were making the doc build fail.
The specs build talks to Launchpad to ensure that there is a blueprint
for each spec being added to the repository. Those calls emit warnings
unless SSL is configured properly, which requires newer SSL libraries
than are available in the standard library.
