aardvark-dns should be improved as the title mentioned, more details can be found here: https://github.com/containers/netavark/issues/855.

Another improvement we can expect is to make sure the name servers in dns_resolver to be unique, otherwise if a name server fails to resolve and it duplicates in the list, it may be tried more than once, that's bad for performance.
