RD-2287 deployment group deploy-on: new ids and naming (#1300) (#1302)

* Use UUID4 for deployment.ids "deployed-on"

Force the new deployments created with "deploy-on" mechanism (a.k.a.
"into environments") have ids populated using UUID4 instead of a
template <environment>-<blueprint_id>-<uuid>.  The former solution might
have had caused excesively long deployment ids, especially in case of
multiple levels of environments, sub-environments (and services).

* Populate display_name for new deployments

* Populate `csys-obj-parent` the same `csys-environment` used to be populated
