[sr-dev] [kamailio/kamailio] acc: skip cdr generation for certain calls (#2348)

### Description I haven't found a way to skip CDR generation per call once [cdr_enable modparam](http://kamailio.org/docs/modules/devel/modules/acc.html#acc.p.cdr… is enabled. ### Expected behavior I have implemented via irontec/kamailio@38964a31d6c0158b7c9bb3abb4e9eb72aa8cd960 adding a new modparam with the dlg_var name that will prevent CDR generation for calls with that dlg_var set. #### Actual observed behavior Once CDR generation is enabled with [cdr_enable modparam](http://kamailio.org/docs/modules/devel/modules/acc.html#acc.p.cdr… all calls generate CDR. ### Additional Information I can make a PR adapting that patch and documenting new modparam, as long as there is no way of achieving it that I have missed and if you find it useful.
