Split run submission and monitoring

[schustmi]

Describe changes

This PR introduces a new method submit_pipeline(...) on the orchestrator interface as a replacement for the prepare_or_run_pipeline(...) method.

For most orchestrators, the prepare_or_run_pipeline method had two main responsibilities:

• Submitting the pipeline to the underlying orchestrator backend
• In case the orchestrator was configured to run synchronous, waiting (and potentially streaming logs) until the run finished

This caused some issues with error handling outside this method, as depending on which phase the orchestrator is in (submitting vs waiting), we want to treat errors differently:

• If there is an error during the submission phase, we want to mark the corresponding run as failed
• If there is an error during the waiting phase, we do not want to mark the run as failed as this might cause downstream problems if some steps of the run are still being executed (e.g. token expiration, status checks)
