cli: add nmcli g logging completionlr/completion-4

This is sort of ugly, because it includes the domain and log levels
verbatim. They're just plain strings on the API, there's no way the
client would know which ones are valid.

On the other hand this kills one of two uses of nmc_parse_args(), which
probably means it's not a very good abstraction and maybe we should get
rid of it altogether. It is in particular unfriendly to argument
completion.
