This change adds a mechanism for charms to be able to update relation data as part of configure_charm rather than responding to an explicit relation event. The reason for this is that pod can be recycled at any point causing it to loose its defered events. So, if a relation adapter method to send relation data contains a defer that deferred event can be lost and when a pod comes back it is never resent.
