Establish better naming conventions for the files being written at the endpoint.

For now it's using the pod name as the file name. This name is sent on streamer.go and written as the file name by the server. In order to give the user flexibility allow naming to be defined as a parameter for the remote file as well. That name could be a single name followed by a random or ordered suffix. It definitely needs to have a better protobuf struct to handle that part between client and server. So it also requires server side changes.
