rABC605bfbfce5a9: [avalanche] Add an API to store and retrieve a proof

Summary

We will need to store proofs that we downloaded and retrieve them for
e.g. relaying. The proof storage is done by the peer manager, which acts
as the valid proof pool and creates a new peer for each new proof. The
interface is provided by the processor so the peer manager remains
private.

Depends on D9617.

504	You'd want to know from this API if it was added or not, but this isn't what's returned.

306	What is the lifetime of that pointer? There is no way this is going to work properly while the proof is owned by the PeerManager is it?

Return an optional proof to get rid of the lifetime issue while keeping the nullable property.
Don't return success if the proof isn't added because already existing, and add test for this case.

I think it's time to start using smart pointers instead of chasing proof copies all around.
