How would you describe the priority of this feature request

Medium

Please provide a clear description of problem this feature solves

This feature will allow evaluating a workflow via the generate endpoint (this feature is mostly there and requires a few minor fixups to be re-enabled) -

1. Start workflow serve same as before -
   aiq serve --config_file=examples/simple/configs/config.yml
2. Run eval with a config file that has the ground truth dataset -
   aiq eval --config_file examples/simple/configs/eval_config.yml --help --endpoint http://localhost:8000/generate

Describe your ideal solution

1. Run workflow via serve
2. Evaluate via endpoint
