[jenkins-ci PATCH v2 17/20] quayadmin: Add list-tags command

[Andrea Bolognani <abologna@xxxxxxxxxx>]

The implementation is limited in that it will not work
properly if a repository contains more than 100 tags, but
that's not really a big concern for us as each repository is
only going to contain a single tag (latest).
