wireprotov2: advertise redirect targets in capabilities

This is pretty straightforward.

Redirect targets will require an extension to support. So we've added
a function that can be wrapped to define redirect targets.

To test this, we teach our simple cache test extension to read
redirect targets from a file. It's a bit hacky. But it gets the
job done.
