Temporarily Disable Linters

This change should disable the Ansible Linters in tox.ini
so that we can make the existing pep8 tests voting.

Linting should be re-enabled in tox once Ansible playbooks
have their errors corrected.

This commit also corrects some python errors that snuck into
Shaker.py
