#### SCAP Security Guide Version:

Amazon Linux 2

#### Steps to Reproduce:

1. I ran ansible-playbook harden-al2.yml

#### Actual Results:
It failed with this errors
```
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: ImportError: No module named selinux
fatal: [localhost]: FAILED! => {"changed": false, "msg": "Failed to import the required Python library (libselinux-python) on ip-172-31-8-206.ec2.internal's Python /usr/bin/python2. Please read module documentation and install in the appropriate location. If the required library is installed, but Ansible is using the wrong Python interpreter, please consult the documentation on ansible_python_interpreter"}
```

#### Expected Results:
It should not fail.

#### Additional Information/Debugging Steps:
We stopped using Python 2. Can I comment it out from the yml file so that it bypasses it?
