Ubuntu 16.04 requires Python 2 about ansible-playbook

[emmanuelstroem]

Because Ubuntu 16.04 and above come with python3,
you need to first set the python3 path in your hosts file like this:
ansible_python_interpreter=/usr/bin/python3
for the initial run of the playbook to install python-simplejson which installs python2 or just python.

Once installed python-simplejson, ansible worked perfectly!
Thank you!
