Title: WIP: Add proxy option to configuration.

This adds a proxy option to the configuration. In the Vagrantfile we can
override this with a specific value and have it passed down to the Fog
API connection options.

The initialization of the Connection object takes a params hash with
the :proxy attribute:

This is wired up from both the Compute and Network OpenStack instances:
