This ansible playbook can be used to install a development version (without Kerberos authentication)
of product-definition-center (PDC, https://github.com/product-definition-center/).
A group 'pdcserver' with at least one machine is required in /etc/ansible/hosts, password-less ssh access 
to root and {{ pdcuser }} (see group_vars/pdcserver) is also a requirement.

Usage:
    ansible-playbook site.yaml

After ansible-playbook has finished, access the configured PDC with a browser on port 8000 like this:
    firefox http://127.0.0.1:8000
(replace 127.0.0.1 with a hostname or an IP if you didn't set up PDC on localhost)
