relation-* events for subordinate charms

[Marco Ceppi]

Hi Iain,

upgrade-charm is the /right/ step for this, however the problem is that
upgrade charm does not explicitly run all the previous hooks (events) that
fired. The files and updated hooks will only be run on future hook
invocations. What I'd recommend is to abstract the bits that do this
updating in the hook to a file that can be included/executed from other
hooks (like the upgrade-charm hook) so that you can refresh them as the
charms are upgraded.
