Merge lp:~cjwatson/launchpad/snap-export-findByOwner into lp:launchpad

[Colin Watson]

Export ISnapSet.findByOwner on the webservice.

It's kind of rubbish to have to use things like `lp.snaps.findByURLPrefix(url_prefix='https://github.com/', owner='/~build.snapcraft.io')` to iterate over BSI's snaps.
