+1 for doing this.

Overall, we need this for AMToken and the ClientAMToken. ContainerToken is a simple pass-through and Localizer stuff isn't public. Right?

> This would allow changing of the TokenIdentifier between versions. The current serialization is Writable. A simple way to achieve this would be to have a Proto object as the payload for TokenIdentifiers, instead of individual fields.
> TokenIdentifier continues to implement Writable to work with the RPC layer - but the payload itself is serialized using PB.
