 Subject: send_as_req re-encodes the request

 krb5_get_init_creds calls encode_krb5_as_req to produce an encoding
 for the preauth plugins, then passes the unencoded request structure
 into the static function send_as_req.  That function re-encodes the
 request.  This is an unnecessary call to the encoder.  In addition,
 for the FAST project, it is desirable to encapsulate the unencoded
 outer request so that krb5_get_init_creds does not need it.

 * send_as_req is modified to take an encoded request and realm
 * Remove unused logic to fill in request nonce from send_as_req
