When reverse proxying pypi the current implementation uses
https to communicate upstream. This works just fine if the
upstream pypi server is serving data via https, but causes
the handshake to fail if the upstream pypi server is serving
via http instead.
This patch implements a check to validate the upstream pypi
server port set and adapts the reverse proxy configuration
appropriately.
