Rebind workloads when their mappings change

[sadlerap]

Signed-off-by: Andy Sadler ansadler@redhat.com

Changes

This works in three stages:

1. During workload mapping's validation webhook, we serialize the old mapping into the servicebinding.io/mapping annotation on all relevant service bindings.
2. We run our reconcile pipeline once, to unbind the workload using the serialized mapping. Once completed, we delete the mapping and immediate trigger reprocessing of the service binding.
3. We re-run our reconcile pipeline as normal using the new mapping to project data as expected.
