Turn off switch for WebRTC to avoid IP address leak

[Dmitry Barnyshev]

Is it possible to append functionality that turns off WebRTC using command line parameter, for example "--disable-webrtc" or using switch in chromium menu, or both variants? It is needed because of dangerous WebRTC IP address  leak https://browserleaks.com/webrtc . Using this leak sites can detect user IP address even when VPN or proxy is used.  Without this switch it is needed to use extension,   to prevent IP address leak for example https://chrome.google.com/webstore/detail/webrtc-leak-shield/bppamachkoflopbagkdoflbgfjflfnfl . This extension uses some amount of RAM and sometimes crashes.

Could you please append this feature in future versions of chromium?
