 Title: #259: RESPONDER: Also populate cr_domains when initializing the responders
Action: opened

PR body:
"""
sss_resp_populate_cr_domains() must be called also when initializing the
responder for basically two reasons:
- Some methods of the IFP responder don't call sss_parse_inp_send(),
causing then the cr_domains to not be populated when
cache_req_select_domains() is called;
- As the operation is not that costly, is better to have it done on
responder's common code in sss_process_init() than just do it in the IFP
responder itself.
