Enable TLS for containerized haproxy

This bind mounts the certificates if TLS is enabled in the internal
network. It also disables the CRL usage since we can't restart haproxy
at the rate that the CRL is updated. This will be addressed later and
is a known limitation of using containerized haproxy (there's the same
issue in the HA scenario). To address the different UID that the certs
and keys will have, I added an extra step that changes the ownership
of these files; though this only gets included if TLS in the internal
network is enabled.
