The manage.py change effectively switches the Zulip production server
to use the virtualenv, since all of our supervisord commands for the
various Python services go through manage.py.
Additionally, this migrates the production scripts and Nagios plugins
to use the virtualenv as well.
Because import_module does not correctly handle safe circular imports we
need to import zerver.models first before the middleware tries to import it.

This includes a hack to preserve humbug/backends.py as a symlink, so
that we don't need to regenerate all our old sessions.
