Configure undercloud for containerized upgrade.

To upgrade undercloud from non-containerized to containerized
it's required to set file with ContainerImagePrepare parameter
defined.
When it's set add registries specified within ContainerImagePrepare
to docker_insecure_registries parameter of uunercloud.conf
