This reverts commit befd8424e2.
Reason for revert:
This change is not needed anymore for A release, especially with
separated-haproxy-service-config feature in place.
It creates a problem now, because haproxy-install.yml is responsible for
creating "base" haproxy service which is required for horizon to work.
If horizon does not work during setup-openstack.yml, tempest tests
may fail(along with the whole upgrade job in our CI)
That's why we need to run haproxy-install.yml, traditionally during
setup-infrastructure.
