commit 63f1542e94f3f1e66cbf0d88f557105ff5d104d0
Author: Tom Clegg <tclegg at veritasgenetics.com>
Date:   Wed Nov 8 16:53:22 2017 -0500

    12515: Use workbenchUrl advertised by API server discovery doc.
    
    Fall back to guessing "workbench."+apiHost (as before) if discovery
    doc does not offer a workbenchUrl (e.g., API server is too old).
