As ContainerizedPlatformComponent support will be removed from K8s plugin, update bp-gen to use ContainerizedServiceComponent nodetype for default blueprint generation (not involving dmaap plugin integration).

service_component_name_override propoerty must be included among default inputs. If this value is set, k8s plugin will use it  to set a fixed DNS/k8s service name for the component. When this value is empty, the plugin will generate random ServiceComponent name.
