  - Pin Werkzeug in lower-constraints
    
    upper-constraints pins Werkzeug to a known working version. The
    lower-constraints job uses a different constraints file, the
    locally-maintained lower-constraints.txt, which didn't pin Werkzeug and
    resulted in the job breaking on the most recent 0.15.0 Werkzeug release.
    This change pins Werkzeug to match the known working version in
    upper-constraints. If and when upper-constraints raises its cap, we can
    address the breakage on the regular unit test jobs.
