Problem: we're not using Ansible pipelining support

[sevein]

This is perhaps more of a question, or a suggestion. When using deploy-pub locally with Vagrant I see that deployments are significantly faster when I enable SSH pipelining with:

[ssh_connection]
pipelining = True

Would it be a good idea to include that directive in the ansible.cfg documents in this repository? It seems like a good default, officially supported by Ansible. Or would that be a conflict with other tools you use like mitogen?
