Because of laptop just have 100M network card and sata disk, so 100 million segment process by collector used 255 second, but cpu just used 28%

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.
