bugzilla: make XMLRPC interface support http and https access
Inadvertently support is currently only for https. For some reason I
thought xmlrpclib.SafeTransport did http and https, but it is https only.
So create http and https XMLRPC transports that retain cookies. Decide which
to use by inspecting the Bugzilla URL.
