Allows us to define different watch versioning regimes in the future as well as to encode information with the resource version. This changes /watch/resources?resourceVersion=3 to start the watch at 4 instead of 3, which means clients can read a resource version and then send it back to the server. Clients should no longer do math on resource versions.
