Like with the compute RPC API, we're unlikely to still work well with RPC client using older 1.x version because of DB schema changes. In that case, we may as well remove 1.x support in Folsom and rip out the potentially buggy backwards compat code. This should also make backporting fixes from Grizzly easier. Deployers following trunk can upgrade all their nodes to use the version 2.0 API before deploying this commit. Change-Id: Iee099751bda9637da5e134357d28e89d5fba9895
