    IPA: Change ipa_server_trust_add_send request to be reusable from ID code
    
    Required for:
        https://fedorahosted.org/sssd/ticket/2639
    
    Expose a request ipa_server_trusted_dom_setup_send that sets up a
    trusted domain. The setup might include actions like retrieving a keytab
    for one-way trusts.
    
    Creating the AD ID context for the trused domain is now done in the
    caller of this new request.
