Refactoring code for podman support

Description

Refactoring code to support Podman

Point of attention

TO DO

• DockerUtils.py:

  • Adapt the right api.pull/build/remove_volume function to podman: [FEATURE] - Add pull/build/remove_volume function for api/image.py as docker py containers/podman-py#456
  • In podman-py listing and filtering image list not working properly: [BUG] images.list() filter does not work properly containers/podman-py#457

  •     for img in images:
            # len tags = 0 handle exegol <none> images (nightly image lost their tag after update)
            if len(img.attrs.get('RepoTags', [])) == 0 or \
                    ConstantConfig.IMAGE_NAME in [repo_tag.split(':')[0] for repo_tag in img.attrs.get("RepoTags", [])]:
                result.append(img)
                ids.add(img.id)

    ConstantConfig.IMAGE_NAME in [repo_tag.split(':')[0] for repo_tag in img.attrs.get("RepoTags", [])]: does not manage well cases where user pulled manually exegol image containing also the registry name, for example docker.io/nwodtuhs/exegol. In this scenario, it won't enter in if statement. It is needed to add any to manage cases where locally I have more container images. [Fixed in PR]

• ExegolImage.py:

  •  def __parseDigest(docker_image: Union[DockerImage, PodmanImage]) -> str:
         """Parse the remote image digest ID.
         Return digest id from the docker object."""
         for digest_id in docker_image.attrs["RepoDigests"]:
             print(digest_id)
             if digest_id.startswith(ConstantConfig.IMAGE_NAME):  # Find digest id from the right repository
                 return digest_id.split('@')[1]
         return ""

    As above, cannot enter in if statement in case user pulled manually an image by specifying docker.io. Need to use in instead of startswith. [Fixed in PR]

    Evaluate if it is needed to manage if statements involving ConstantConfig.IMAGE_NAME in other files to manage the presence of prefix docker.io in the image name.

• ExegolController.py - Import podman and manage console.print_exception(show_locals=True, suppress=[docker, requests, git]) to consider podman module too.

• ConstantConfig.py:

  • Review Desktop path for Windows and Mac in case of podman
  • Implement the same from docker.types import Mount for podman: [FEATURE] - Implement Mount type containers/podman-py#458
