recording-daemon : notify-purge param removes a file if notify success

[sewan-aprodhomme]

Hi,

We wanted rtpengine to remove records when a notify was successful. We implemented it.
When a POST request success, we remove the output file if notify-purge option is enabled.

I suppose this option only makes sense if notify-record is also set? Perhaps add a safeguard to protect against wrong usage, and/or mention it in the docs?

I changed the documentation and the if (notify_record && notify_purge) { accordingly.
I hope it's better now. Tell me if you see something that's still bad !
