Error: list index out of range in diffparam_healthcheck

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind bug

Description

exception thrown trying to process state of running container, when playbook trying to determine if the container needs to be created. Verified that this happens when the image declares "HEALTHCHECK none" in the dockerfile. Appears the module expects that there's a health check command.

Steps to reproduce the issue:

Create an image, that declares "HEALTHCHECK none" in the docker file, and create image.
Create playbook that uses the podman_container module, don't create/configure any healthcheck properties in the playook
Run the playbook to create container, then run playbook again with running container.

Describe the results you received:

playbook fails, Exception, list index out of range

Describe the results you expected:

expected on 2nd run, no configuration changes made, playbook doesn't change container, completes successfully

Additional information you deem important (e.g. issue happens only occasionally):

Happens when image defined with "healthcheck none". note podman doesn't seem to recognize this either, it creates a systemd healtcheck entry, even though there's actually no healthcheck.

Version of the containers.podman collection: Either git commit if installed from git: git show --summary Or version from ansible-galaxy if installed from galaxy: ansible-galaxy collection list | grep containers.podman

can't run from ansible tower, should be 1.10.1
