Enable TLS configuration for containerized HAProxy

In non-containerized deployments, HAProxy can be configured to use TLS for
proxying internal services.

Fix the creation of the of the haproxy bundle resource to enable TLS when
configured. The keys and certs files are all passed as configuration files and
must be copied by Kolla at container startup.

For the time being, disable the use of the CRL file until we find a means
of restarting the containerized HAProxy service when that file expires.
