SSL certs configuration in licode_config.js?

Are these SSL settings even used anymore?

config.erizoController.ssl_crt = ‘<ssl_crt>’;
config.erizoController.ssl_key = ‘<ssl_key>’;
config.erizoController.ssl_ca = ‘<ssl_ca>’;

I couldn’t find any reference to them in the code base. If I remember
correctly someone mentioned these settings in the forums a long time ago in
reference to turnserver support. I’m just not seeing how they are used.
