KV store stale data harvester

When attempting to clean up the KV store during various operations, such as device deletions and adapter restarts, there is a possibility that lower-level KV store deletes fail and leave orphaned data in the KV store. Over time this could lead to KV store bloat over time.

A garbage collector/harvester should be developed that can identify orphaned data in the KV store and attempt to remove it. This harvester can then be periodically run against the KV store.

As a recommendation, having this as a separate process that you can run as a K8s job might be a good implementation choice.
