/kind bug

Description

The list processes API endpoint for pods and containers both don't seem to support streaming.

This affects version 3.4.x, I have not tested the development version 4.x since the project I'm working on is targeting 3.4.x and 4.x will contain breaking API changes.

Steps to reproduce the issue:

1. podman system service unix:///home/`whoami`/testing.sock --log-level=debug --time=500 with running pod and container.

2. curl -X GET --unix-socket "/home/`whoami`/testing.sock" "http://d/v3.0.0/libpod/containers/test_container/top?stream=true" or curl -X GET --unix-socket "/home/`whoami`/testing.sock" "http://d/v3.0.0/libpod/containers/test_container/top" since streaming should be true by default according to the reference.

3. curl -X GET --unix-socket "/home/`whoami`/testing.sock" "http://d/v3.0.0/libpod/pods/test_pod/top?stream=true" or curl -X GET --unix-socket "/home/`whoami`/testing.sock" "http://d/v3.0.0/libpod/pods/test_pod/top" since streaming should be true by default according to the reference.

Describe the results you received:
One response.

Describe the results you expected:
Multiple responses streamed over time.
