• grpc-proto RPC prototypes: merged change

From the original issue:

service NamespaceService {
  rpc AddNamespace(AddNamespaceRequest) returns (AddNamespaceResponse) {}
  rpc RemoveNamespace(RemoveNamespaceRequest) returns (RemoveNamespaceResponse) {}
  rpc RenameNamespace(RenameNamespaceRequest) returns (RenameNamespaceResponse) {}
  rpc FileExists(FileExistsRequest) returns (FileExistsResponse) {}
}

message AddNamespaceRequest {
  string storage_name = 1;
  string name = 2;
}

message RemoveNamespaceRequest {
  string storage_name = 1;
  string name = 2;
}

message RenameNamespaceRequest {
  string storage_name = 1;
  string from = 2;
  string to = 3;
}

message FileExistsRequest {
  string storage_name = 1;
  string name = 2;
}

message FileExistsResponse {
  bool exists = 1;
}

I checked through the proto definitions, and the pasted code block looks up to date
