veyron/services/mgmt/node/impl: Add proxy invoker for pprof and stats

proxyInvoker is an ipc.Invoker implementation that proxies all requests
to a remote object, i.e. requests to <suffix> are forwarded to
<remote>/<suffix> transparently.

It is used by the node manager to proxy the stats and pprof objects of
running apps.
