    Description

      SERVER-58752 introduced the ability to retry an aborted prepared (on a subset of participant shards) transaction by retrying the transaction with a higher txnRetryCounter (internal client only). To support re-committing the transaction, we will need recreate a TransactionCoordinator (i.e. add txnRetryCounter to the TransactionCoordinator classes like we did for TransactionRouter and TransactionParticipant).
