KMS Encrypt and Decrypt filters in Ansible

KMS Encrypt and Decrypt Filters for Ansible

This Gist shows how you can encrypt/decrypt variables with KMS during your Ansible playbook execution. While google searching I couldn't find anything useful on the subject.

Let's say your project has a folder of playbooks called plays.

In that folder, create a folder called filter_plugins and insert kms_filters.py (included in this gist)
