I opened PR 4638 [1] a little over a month ago to remove legacy subject indexing in the auth database (which predates a bijective mapping from namespaces to keys).
This PR introduces a new subjects view (v2) and removes the old view. Operators can still use the old view because the view is now programmable at deployment time (from a previous PR). Sven if you're able to review this PR, your input would be appreciated. Otherwise, will proceed to merge by silent assent after 48 hours. [1] https://github.com/apache/openwhisk/pull/4638 -r
