Conversation
Adds a configurable mapping between PostgreSQL CR annotations and EBS
volume tags. The operator reads the configured annotation keys from the
CR metadata and applies them as tags on the associated EBS volumes during
each sync cycle.
Tags are compared against existing EBS tags (extracted from DescribeVolumes,
which is already called for volume management) and CreateTags is only called
when a tag is missing or has a different value, avoiding unnecessary AWS API
calls on steady state.
Configuration example in the operator ConfigMap/OperatorConfiguration:

Summary
This is another approach to solve the same problem as #3123, but the other approach seems cleaner and more generic.
