Cromwell preemption and error retry interaction with GCP Batch built-in retry

[aednichols]

How does it work? Does Cromwell still have the chance to evaluate failure retries against e.g. exit codes?

There was a brief explanation in #7457, right now, Cromwell is able to parse Batch exit codes but these are not being used to do any manual retries but a similar strategy to PAPI can be implemented.
