[jraddaoui]

Related to artefactual-sdps/enduro#1087 and artefactual-sdps/enduro#886.

• Generate a UUID in the preprocessing workflow and add it to the result.
• Receive preprocessing UUID in AIS workflow.
• TODO:
  • Preprocessing: send metadata file to AIS bucket.
  • AIS: fetch metadata file from AIS bucket.
  • AIS: remove METS parsing code.
  • AIS: remove metadata file download from AMSS.
  • AIS: remove metadata file from AIS bucket when the bundle has been stored.

Sadly, temporalio/sdk-go#916. That's why I went with an UUID generator.

Why not use the WorkflowID from the processing Workflow? You'd have to pass it to preprocessing and postprocessing too, but it's a unique identifier that is tied to the Workflow execution, and you can set it in test as well.
