veyron/services/mgmt/impl: code refactoring to split up invoker.go
Split up the RPC method implementations from invoker.go into node_invoker.go,
app_invoker.go, and config_invoker.go, with three separate invoker types. Also
split up internalState accordingly.
Move methods shared by more than one invoker into util.go.
Remove vlog at the beginning of each method. It's verbose, and we can do this
type of logging better in the ipc framework.
Remove counter.go (unused).
Get rid of the internal Node vdl interface, and instead keep Config separate,
which is simpler.
