Subject: [PATCH 42/48] IPA/AD/SDAP/BE: Generate refresh callbacks with a macro

Related: https://pagure.io/SSSD/sssd/issue/4012

The per-object type refresh functions are more or less boilerplate code.

Even though macro-generated code should be used very rarely, here the

generated code does not contain any logic at all so it makese sense to

generate it with macros.
