Bug 20985: Add OnShelfHoldsAllowed checks to CanItemBeReserved

The expected behaviour for "On shelf holds allowed" setting for the circulation
rules (Koha administration > Patrons and circulation > Circulation and fines
rules):
- Allow holds only on items that are currently checked out or otherwise
unavailable.
- If set to "Yes", patrons can place holds on items currently checked in.
- If set to "If any unavailable", patrons can only place holds on items that
are not unavailable.
- If set to "If all unavailable", patrons can only place holds on items where
*all* items on the record are unavailable.
(Adapted from

These rules should also work when using ILS-DI, but currently they don't. This
bug makes sure that the "On shelf holds allowed" rules work correctly when
using ILS-DI to place holds.

Test plan:

1. Enable ILS-DI (set the ILS-DI system preference to Enable).
2. Go to Koha administration > Patrons and circulation > Circulation and fines
rules.
3. Work through steps 4-5 for each of the settings for "On shelf holds allowed"
for all libraries/patron categories/item types:
   . "Yes", "If any unavailable", and "If all unavailable"
4. Staff interface - place a hold on a record with items available for loan,
the rules should work as expected before and after the patch is applied:
   . "Yes"
      ==> information column in the item table displays "Not on hold", the hold
is placed, cancel the hold
   . "If any unavailable" and "If all unavailable"
      ==> the hold is not placed, message is "Cannot place hold. No items are
available to be placed on hold.", red "X" in the hold column and the
information column displays "Not on hold".
5. ILS-DI - place a hold on a record with items available for loan (note:
without the patch, holds can be placed):
   . Query to place a hold using ILS-DI on a title that have all its items
available,
     example query:
http://127.0.0.1:8080/cgi-bin/koha/ilsdi.pl?service=HoldTitle&patron_id=1&bib_id=1&request_location=127.0.0.1
     ==> Without the patch the hold is placed but it shouldn't be allowed,
cancel the hold
   . Query to place a hold using ILS-DI on an available item,
     example query:
http://127.0.0.1:8080/cgi-bin/koha/ilsdi.pl?service=HoldItem&patron_id=1&bib_id=1&item_id=1)
     ==> Without the patch the hold is placed but it shouldn't be allowed,
cancel the hold
6. Run the tests prove t/db_dependent/Reserves.t - these should pass.
7. Apply the patch (and flush_memcached and restart_all if using
koha-testing-docker).
8. Run through steps 3-6 again, and note the changes when "If any unavailable"
and "If all unavailable" options are used:
   . For the staff interface: there should be no change in behavour and should
work as expected, for the red "X" in the items table additional text is added
"onShelfHoldsNotAllowed".
   . For ILS-DI: these should now work as expected, with holds not placed, and
this message in the results returned <code>onShelfHoldsNotAllowed</code> (check
to confirm no holds place for either the patron or the item)
   . Tests: should still pass.
9. Sign off.
