Listener options for Ironic/ceilometer/glance_registry

Listener options for Ironic/ceilometer/glance_registry

This updates some of the listener options set by loadbalancer.pp.

Iroinc needs to pass in the option to do a httpchk, otherwise
puppet-haproxy defaults it to doing a ssl-hello-chk, which won't work
against the non-ssl loadbalancer server.

Ceilometer and glance_registry both don't support a httpchk against the
root (/) of their webservers (they return a straight 401) so disable
those checks completely.
