ansible - pretty printing errors

Ansible does not do a great job at pretty printing exceptions/errors. There are plugins available that make this easy.

mkdir -p ~/ansible/plugins/callback
cd ~/ansible/plugins/callback
wget https://raw.githubusercontent.com/marcosdiez/ansible_human_log.py/master/human_log.py

create/edit ~/.ansible.cfg and add the following to the defaults section,

[defaults]
callback_plugins = ~/ansible_plugins/callback

Done!
