upgrades: deploy mod_ssl when upgrading apache

1) When Apache is upgraded, install mod_ssl rpm.
   See https://bugs.launchpad.net/tripleo/+bug/1682448
   to understand why we need mod_ssl.

2) All services that run Apache for API will use the snippet from
   Apache service to deploy mod_ssl, so we don't duplicate the code
   in all services. It's using the same mechanism as ovs upgrade to
   compile upgrade_tasks between both services.
