Kevin Carter 8ae51276c4 Update HAProxy for multi-OS support
This change implements CentOS7 and Ubuntu 16.04 support for the HAProxy
role. Because RHEL does not package HATop the installation of HATop has
been moved to a source installation so that it can be used universally.

Implements: blueprint multi-platform-host
