For traffic to unknown addresses, or to workloads that are not a part of the mesh, the traffic will just be passed through as is.
To make ztunnel more transparent, the original source IP address will be spoofed.
Additionally, `splice` will be used to make this proxying more efficient when possible.

For traffic in the mesh, things are a bit more complex:

1. If the destination has a waypoint proxy, we must send to it to the waypoint (using HBONE).
