Server name indication is a way for a server to present multiple TLS certificates from a single IP address. As of OTP 20 the SSL application passed back the SNI information to the client so that it can be validated.
We restore the previous behavior by disabling this functionality explicitly.
The SNI disable option has existed since at least OTP 17 so it ought to be safe for several previous OTP releases.
Closes #11
