Export Inventory Holdings to a delimited file format

The user should be able to trigger the export of holdings records by providing records identifiers and export the records into delimited format. For the initial implementation the delimiter will be predefined (comma or pipe characters) but in the future implementation, the delimiter should be configurable.

The user should be able to:

• export the entire holdings record
• select fields from holdings records to be included in the export
• select fields from instance and items records that should be included in the export in addition to the holdings record

Note:

• Export in MFHD - is covered by UXPROD-1396 and UXPROD-142
• Inventory Holdings JSON format - with human readable labels instead of UUIDs - is covered by UXPROD-2705
• Including holdings data as a part of the MARC Bib record is covered in UXPROD-2153 and UXPROD-2413
