## Streaming Requests

Streams consists of an initial request with payload and allows for full two-way communication between the client and server.

The handler function has this signature.

Sample handler:
```go
    handler :=  func(ctx context.Context, payload []byte, in <-chan []byte, out chan<- []byte) *RemoteErr {
        fmt.Println("Got request with initial payload", p, "from", GetCaller(ctx context.Context))

## Urgent Upgrade Notes 

### (No, really, you MUST read this before you upgrade)

  - container_cpu_usage_seconds --> container_cpu_usage_seconds_total
  This is a partial revert of [#86282](https://github.com/kubernetes/kubernetes/pull/86282), which was added in 1.18.0, and initially removed the _total suffix ([#89540](https://github.com/kubernetes/kubernetes/pull/89540), [@dashpole](https://github.com/dashpole)) [SIG Instrumentation and Node]
