Return ItemRecordID in responses to BibHoldingsGet
A recent change to PAPI allows for the retrieval of, and adding to, different types of records sets, including Patrons, Bibs, and Items. Adding to Patron and Bib records sets is straight forward because there are existing endpoints within PAPI that return BibRecordID and PatronRecordID numbers. This isn't the case with Item record sets because there a currently no endpoints that provide an item's RecordID. This enhancement would add the ItemRecordID to each row in the BibHoldingsGet response.
