Save exchanged and not exchanged data to storage.  e.g.  node reference, A -> B will be 1->2 or 1->10.0.0.1

2. Instance discovery table and data define finish.

2. make stream module as a collector define module, contains grpc remote service for call remote workers
3. worker framework is ok
4. Collector start ok

1. remote worker use common service, send data object with bytes and data define id, use define id to find the grpc deserialize object.
2. merge the metric data and record data to data object.

2. Add context help for every module to find another module’s context.

refactor ClusterContext and LocalContext implements Lookup interface that let the user of context just use lookup or findprovider method.

2. created workerref class use for cover akka actorref class
