Option to configure alternatives to HMAC-SHA1

[dkrivoruchko]

It will be nice to have the option to configure more secure alternatives to HMAC-SHA1. Like HMAC-SHA256. In general, SHA2 will be nice and SHA3 will e perfect!

RFC: https://datatracker.ietf.org/doc/html/draft-uberti-behave-turn-rest-00#section-2.2 HMAC-SHA1 is one HMAC algorithm that can be used, but any algorithm that incorporates a shared secret is acceptable, as long as both the web server and TURN server use the same algorithm and secret.
