Replace ansible.module_utils.six imports with Python 3 stdlib and add…

[chynasan]

Backport of #286 to stable-5.

Since ansible-core 2.20 introduced a new pylint check (ansible-bad-import-from) that flags imports from ansible.module_utils.six, when a stdlib equivalent exists:

• Replaced iteritems() with dict.items() in 3 files
• Replace string_types with str in openshift_import_image.py
• Add tests/sanity/ignore-2.20.txt for validate-modules errors
• Add tests/sanity/ignore-2.21.txt for validate-modules errors

For issue #253

Hi @chynasan. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
