Add docs publish docs for grenade

This commit adds docs jobs to grenade. Previously grenade didn't have
support for building docs and just relied on having rst files in the
repo. Now that doc building mechanism from devstack was ported over
to grenade this adds the necessary jobs to publish the resulting
rendered documentation.
