sijie opened a new pull request #1448: [table service] use grpc reverse proxy to serve storage container requests
URL: https://github.com/apache/bookkeeper/pull/1448
 
 
   Descriptions of the changes in this PR:
   
   *Motivation*
   
   #1430 introduced client interceptor and grpc reverse proxy for storage container requests. This PR is the subsequent change to leverage client interceptor and reverse proxy for storage container requests.
   
   *Changes*
   
   **Client Changes**
   
   Changed `StorageContainerChannel` to add client interceptor to stamp storage container id into the the requests' metadata.
   
   **Server Changes**
   
   - moved the stream storage logic out of storage containers to a `service` package. the main logic will be kept in `RangeStoreService` and `RangeStoreServiceFactory`.
   - make the storage container logic for hosting `StorageContainerService`.
   - Each storage container will run an inprogress grpc server for serving the grpc services registered to the container and provide an `channel` for accessing those grpc service.
   - Changed the server to use reverse proxy for serving/proxying storage container requests.
   
   *NOTE*
   
   This change doesn't directly remove `StorageContainerRequest` and `StorageContainerResponse`.  It would be done in a subsequent change.
