nginx configuration

[ctapobep]

A cookbook is needed to install and configure nginx.

Acceptance Criteria:

• Configuration should include jcommune, poulpe, antarcticle projects.
• It should be possible to add minor updates (DNS name) in order to get the apps running on production servers. That config is going to be a sample to be used by possible admins.
• It should be possible to use external resources (file, git repo, chef support?) to grab actual nginx configuration. The approach should be pretty generic because configs for other utils are going to be installed in a similar way.

NB: I can provide sample configuration from production.
