Bug 28480: Add q parameters for GET /patrons

This patch adds the q query parameters to the route.

To test:
1. Try the route with the following query parameter:
   q={"patron_id":2}
   i.e. GET /api/v1/patrons?q={"patron_id":2}
=> FAIL: You get a bad request respose
2. Apply this patch
3. Restart all
4. Repeat 1
=> SUCCESS: You get the patron
5. Sign off :-D
