> In clusters with many members, a View can be large. See if we can compress views. Possible strategies:
> - Canonicalization of addresses (replace UUIDs with shorts) see different JIRA)
> - Compress digests (see different JIRA)
> - Keep a list of ViewIds and Views and only send the ViewIds (not for JoinRsp !)
> - Create a DiffView: send the previous ViewId V1, the new ViewId V2, and the diff between V1 and V2, for example
>   - V34=V33 + N1 + N2
>   - V34=V33 - N30 - N13 + N3 (2 nodes left, 1 node joined)
>   - The receiver can then construct a full view from V34, V33 and the diffs
