Add custom APIObject serializer and de-serializer for pickle module

[jakurban]

The pickle module implements binary protocols for serializing and de-serializing a Python object structure and with the default serializer it wasn't possible to serialize APIObjects, therefore it is necessary to create a custom one.

Hi @JaurbanRH. 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.

/ok-to-test
@JaurbanRH I've applied the label to test, but it's going to fail because you'll need to run the ./ansible/rebuild_module.sh locally and include the updated files.
