netplan: Don't render yaml aliases when dumping netplan
Cloud-init rendered netplan with duplicate aliases if a network config included "global" nameserver/search values. Netplan uses can read yaml files which do use aliaes but cloud-init did not render a single yaml dictionary, instead it combined yaml sections into a single document which sometimes resulted in duplicate aliases being present. This branch introduces a yaml SafeDumper class which can set the 'ignore_aliases' attribute. This is not enabled by default but callers to util.yaml_dumps can pass a boolean to toggle this. The netplan render uses noalias=True and the resulting yaml output does not contain any aliases. LP: #1815051
