We do not need gerrit-git-prep anymore, zuul-git-prep works on all our
slaves and has the advantage of using zuul-cloner so that the local
cache is used and Depends-On works.
Remove gerrit-git-prep and use zuul-git-prep instead everywhere.

Across the entirety of our job config corpus, we only ever set the
tarball-site parameter to tarballs.openstack.org. Instead just set
it directly in the publishers where it's needed and reduce
unwarranted confusion for people writing job configs. This also
allows us to get rid of the parameterized sites in the tarball,
wheel and war publishers.

Add an initial job to exercise the signing node, which can retrieve
tarballs and wheels, sign them and upload those signatures. Only use
it for the git-review project to start, while we iron out any bugs.
