[OSSN-0086] erratum: Dell EMC ScaleIO/VxFlex OS Backend Credentials Exposure
As you may recall, the fix for this issue required patches for both
Cinder and the os-brick library.
The original patch for os-brick contained a flaw  that prevented the
scaleio connector from operating when run under Python 2.7. Thus for
OpenStack releases supporting Python 2.7 (that is, Train and earlier), a
second os-brick patch is required and is listed below. (The Cinder and
first os-brick patch are unchanged, but are listed below for completeness).
