APIv2 tests: python something != something-podman

[edsantiago]

Seeing this occasionally since Dec 30:

________________________ ContainerTestCase.test_attach _________________________
         
         self = <python.rest_api.test_v2_0_0_container.ContainerTestCase testMethod=test_attach>
         
             def test_attach(self):
                 r = requests.post(
                     self.podman_url + "/v1.40/containers/create?name=topcontainer",
                     json={"Cmd": ["sh", "-c", "echo podman; sleep 100"], "Image": "alpine:latest"},
                 )
                 self.assertEqual(r.status_code, 201, r.text)
                 payload = r.json()
             
                 r = requests.post(
                     self.podman_url
                     + f"/v1.40/containers/{payload['Id']}/start"
                 )
                 self.assertEqual(r.status_code, 204, r.text)
             
                 r = requests.post(
                     self.podman_url
                     + f"/v1.40/containers/{payload['Id']}/attach?logs=true&stream=false"
                 )
                 self.assertIn(r.status_code, (101, 200), r.text)
                 # see the attach format docs, stdout = 1, length = 7, message = podman\n
         >       self.assertEqual(r.content, b"\x01\x00\x00\x00\x00\x00\x00\x07podman\n", r.text)
         E       AssertionError: b'' != b'\x01\x00\x00\x00\x00\x00\x00\x07podman\n' :
         
         test/apiv2/python/rest_api/test_v2_0_0_container.py:155: AssertionError

If I read the URL correctly, this has something to do with logs, and ISTR other flakes in podman-remote logs but can't find the issue number.

Problem is that it needs a running container which already logged the message when it calls call attach to reproduce the bug. I assume that CI is just to slow so the message was not logged yet.

I will fix come up with a fix tomorrow.
