Testing - Update batch of bibs

[ahafele]

• Set up ebsco tools/airflow
• Dump batch of bib records from -test or -stage. Could use file generated by an existing Data Export process.
• Edit, e.g. add 6xx $0 with https://id.loc.gov/authorities/subject/TEST
• Reload with batch endpoint
• Review data and process for errors

Leverage existing OCLC workflow:
We retrieve the instance uuid from the 999 field
With instance uuid, we query the source-storage endpoint to retrieve the latest SRS uuid
We then use the change-manager endpoint to PUT the MARC record using the SRS uuid retrieved from the previous step
