HBONE is just a standard HTTP `CONNECT` tunnel, over mutual TLS with mesh (SPIFFE) certificates, on a well known port (15008).
The target destination address is set in the `:authority` header, and additional headers can be included as well.
Currently, only HTTP/2 is supported, though HTTP/1.1 and HTTP/3 are planned.

Currently, SNI is not set by Istio clients and ignored by Istio servers.
