For NFV deployments, specific kernel args should be applied and
the nodes should be restarted before running the NetworkDeployment.
It is supported in the heat deployment via PreNetworkConfig. In the
config-download mechanism, ansible steps need to be improved
to handle the reboot and wait for the node.

Updates overcloud-resource-registry.j2.yaml to include the mappings from
enviornments/config-download-environment.yaml. This enables
config-download by default. The environment to explicitly enable
config-download is deprecated.
An environment at environments/disable-config-download.yaml is added
which can be used to disable config-download but is marked as
deprecated.
