Sample call:
```go
    // Get a connection to the remote host
    conn := manager.Connection(host)
	
    payload := []byte("request")
    response, err := conn.SingleRequest(ctx, grid.HandlerDiskInfo, payload)
```

If the error type is `*RemoteErr`, then the error was returned by the remote server. Otherwise it is a local error.
