Retry with More Memory as workflow option

The experimental memory retry feature gains per-workflow customization and includes breaking changes:

• The per-backend configuration key <backend>.config.memory-retry.error-keys has been removed and replaced
  with global key system.memory-retry-error-keys
• The per-backend configuration key <backend>.config.memory-retry.multiplier has been replaced with workflow option
  memory_retry_multiplier

More details can be found here.

Bug Fixes

• Fixed a bug that caused Cromwell to mark workflows as failed after a single 500, 503, or 504 error from Google Cloud Storage.
  • Cromwell will now retry these errors as designed.
  • The default retry count is 5 and may be customized with system.io.number-of-attempts.
