As part of this, we need to pick the correct certificate to serve on behalf of the destination workload.
As discussed in [HBONE](#hbone), this is based on the destination IP.
Additionally, we enforce the peer has a valid mesh identity (but do not assert _which_ identity, yet).

Next, we terminate the CONNECT.
From the [headers](#headers), we know the target destination.
