Code Issues Proposed changes

Do more robust checks against zuul-web with haproxy

Browse Source 
Switch the port 80 and 443 endpoints over to doing http checks instead
of tcp checks. This ensures that both apache and the zuul-web backend
are functional before balancing to them.

The fingergw remains a tcp check.
