This was added by commit de7975c--Gerrit change 7--so old it
predates Change-Id headers in the repo (and, apparently, commit
messages). Today it seems to be completely unused. The pubring.gpg
contained just this one key:
pub 2048R/32EE128C 2010-08-15
uid OpenStack Hudson <hudson@openstack.org>
sub 2048R/92E212FC 2010-08-15
Based on discussion in IRC, Monty vaguely recalls this might have
been related to DEB package building once upon a time (something we
no longer do and wouldn't configure from this module anyway when
eventually want to start doing again).
