Bug 31791: Add x-record-source-id header to POST /biblios

Bug 31791: Add x-record-source-id header to POST /biblios

This patch adds support for setting the record source on the API. It
does so by adding support for a new header `x-record-source-id`.

Setting the record source is restricted to patrons with the
`set_record_sources` permission.

A 403 error is returned on an attempt to set it without the correct
permissions.

The feature is documented on the spec.

To test:
1. Apply this patch
2. Run:
   $ ktd --shell
  k$ prove t/db_dependent/api/v1/biblios.t
=> SUCCESS: Tests pass! Tests cover the right use cases!
3. Play with Postman (or similar)
4. Sign off :-D
