Example HAProxy configuration

This role can be applied to a new host, it will proxy traffic back to N number of 'rgws'. In practice you will ideally want to have incoming traffic on one network interface and backend traffic on another network interface on the haproxy machine.

I didn't enable this role in the example site.yml as I believe it is better for the user to take whats there and either use it as is or integrate parts of the config in existing infrastructures.

Also this role currently just works on ubuntu and it does not explain much about SSL termination strategies etc... although there is a https block in the config which does do ssl termination on the haproxy machine.
