Removed last bits of code relating to "Bypass proxy server for local addresses" option.
New proxy settings are sent from XenCenter to health check service and used to configure the proxy using GetProxyFromSettings().
Health check service now correctly saves its proxy settings and updates the static Proxy property for the Session class; done in new ReconfigureConnectionSettings().
