feature: python 3.X support

[AJMKing]

ansible has a drama with loop: {{ foo.keys()}} this can be changed to with_dict: {{ foo }} and {{ item.key}}

further investigation is required

I just noticed this when updating Ansible on the DAC nodes:

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support
