CTP, onInvalidMessage not implemented

[Inode1]

Description:
The onInvalidMessage field defined in the ClientTrafficPolicy is not currently passed to the IR.

We could use buildIRHTTP2Settings insted of translateHTTP2Settings for CTP.

I think that it's a case where a shared struct was extended for the BTP case, but not implemented for CTP. Envoy supports this option in HCM, so there's no reason to not implement it... It's possible that the two functions mentioned by the user use different secure defaults, so I'm not sure that they interchangeable.
