////////////////////////////////////////////////////////////////////////////////
//
// WorkerService defines a TensorFlow service that executes dataflow
// graphs on a set of local devices, on behalf of a MasterService.
//
// A worker service keeps track of multiple "registered graphs". Each
// registered graph is a subgraph of a client's graph, corresponding to
// only the nodes that should execute on this worker (and any
// additional nodes necessary for inter-process communication using
// the `RecvTensor` method).
