If a receiving Orion is available when the private transaction is distributed but is unavailable
when the privacy marker transaction is processed, the private transaction is not executed by
the receiving Besu node. The private states in the Besu nodes are then inconsistent.
1. Retain current behaviour and clearly doc requirement and strategies to ensure HA
2. Stop Besu when private tx unable to processed due to Orion being down. When Orion is back up, resync chain from point it stopped at
3. Log a message and provide a way to resync over skipped private transactions from the point they stopped being processed
