lei q|up: support v2:/path/to/inboxdir destination

This allows "lei-managed pseudo mailing lists" as described
by Konstantin.

Alternates use is optional and can be enables via --shared.

This doesn't manage or edit ~/.public-inbox/config; presumably
there'll need to be some tweaking of search parameters before
finalizing and making the inbox publicly accessible via HTTP/NNTP.
