Update HAProxy role for Production use

Registered by Jean-Philippe Evrard

HA Proxy can be improved by adding a few changes:
- Deploying it with Keepalived, to bring HA to haproxy
- Allowing configuration interface to easily adapt load
- Adapting the default configuration and the services deployed with the inventory. This way we can only deploy what's used
- Adapting default timer values to be more efficient.
