Bug 24528: Add *_count support to to_api

This patch adds a way to tell to_api an attribute needs to be calculated
as the count on an existing method/relationship result. For example, if
we wanted to include the holds_count attribute for a Koha::Patron
object, we would call it:

    $ patron_json = $patron->to_api({ embed => { holds_count => { is_count => 1
} } });

This way to_api will internally call

    $json->{holds_count} = $self->holds->count;

To test:
1. Apply the tests patch
2. Run:
   $ kshell
  k$ prove t/db_dependent/Koha/Object.t
=> FAIL: Tests fail!
3. Apply this patch
4. Repeat (2)
=> SUCCESS: Tests pass!
5. Sign off :-D
