Use TLS proxy for neutron server's internal TLS

This uses the tls_proxy resource added in a previous commit [1] in
front of the neutron server when internal TLS is enabled. Right
now values are passed quite manually, but a subsequent commit will use
t-h-t to pass the appropriate hieradata, and then we'll be able to
clean it up from here.

Note that the proxy is only deployed when internal TLS is enabled.
