Implemented wildcard selector (based on #238) (#488)

* Initial check-in of wildcard to get all secrets in path (Issue#234)
* Fix wildcard for K/V v2 and Cubbyhole.  Add more tests
* Refactored out selectAndAppendResults
* Use selectAndAppendResults for wildcard
* Use normalizeOutputKey in action.js
* Refactored wildcard
