Support list tags for cli

Does hugo cli support list tags?

Hi!

I’d like to know Is it possible in the future to get a list of tags in stdout?

$> hugo list tags
$> hugo list categories

I do not need up-to-date information. Cache is also good.

May be I very old? Tell me, if this is nonsense, I will close this topic.

Otherwise I’d like suppose this feature.

Best, Alex.
