Inject TLS certificate and keys for the Overcloud

This is a first implementation of adding TLS termination to the load
balancer in the controllers. The implementation was made so that the
appropriate certificate/private key in PEM format is copied to the
appropriate controller(s) via a software deployment resource.

And the path is then referenced on the HAProxy configuration, but this
part was left commented out because we need to be able to configure the
keystone endpoints in order for this to work properly.
