Fix ansible.cfg settings

- using %Y-%m-%d in ansible_managed message is not recommended
as deploying from a new git checkout will change the ansible_managed
string in the template and Ansible will report the template file as changed
(see http://docs.ansible.com/ansible/intro_configuration.html#ansible-managed )
- no such setting called role_path (see
http://docs.ansible.com/ansible/intro_configuration.html )
- scp_if_ssh should be under [ssh_connection] header
