Satellite bugs have a PM score. When a Redmine issue is associated with a Bugzilla, it would be useful to have the Bugzilla PM score also stored on the upstream bug. To accomplish this we should:

1. Add a non-public field named 'Satellite PM Score'. This field should have similar visibility as the existing 'Bugzillas' [0] field.

2. Extend the redmine_bugzilla.py [1] script to do the following pseudocode:

if the upstream bug has exactly 1 downstream bug:
    composite_score = the PM score on the downstream bug
else:
    composite_score = sum(all downstream bug PM scores)
if composite_score != to the upstream PM score:
        update the upstream issue with the composite_score

In practice the implementation should likely save a list of upstream bugs with > 1 downstream BZ associated with it and handle those as a loop dedicated propagating the summed PM score to the upstream bug.
