why do the other types use tls.Sni but here we use sniName?

Good catch we have to set tls.Sni if it exists and if it does not exist for ISTIO_MUTUAL we will have to set the default SNI name. This was existing implementation

Looks like for ISTIO_MUTUAL we only honor the sniName not the ones given in tls.Sni. So the existing implementation is correct.

Ignore the above. I corrected the code. If tls.Sni exists we use it otherwise use the default sniName. All tests are passing now. PTAL

#26684 did not fix the custom sni properly. It did not add it correctly to the upstream tls settings. This PR fixes it.
