Provide options to sort or filter tags, return tag metadata

[stevenschlansker]

Currently, the tags API is very minimal. It only provides a mapping "tag" -> "id"

We want to be able to select tags by a couple of criteria - date, user, etc. It would also be nice to return this data in a tag object. Finally, sorting by date would be helpful.

I don't think the date is stored with the tag at all, but you may be
able to figure out the user by looking through the signatures
(moby/moby#8093). In any case, this feels like a job for an
external search index to me (#687).
