Subject: [PATCH 2/2] Fix "Remove VxFlex OS credentials" regression

Change I10a8aaddbf7dd09830cd4189cd1f99c0ad1f3b60 uses a ConfigParser
instance in a way that is incompatible with python 2.7, resulting in
a "ConfigParser instance has no attribute '__getitem__'" error.  This
patch accesses the ConfigParser using the "old" API that works in both
Python 2.7 and Python 3 and adds some tests.

(cherry picked from commit 750999db0de0fcfc923cd453add808ca42a4e2b4)
Conflicts:
- remove os_brick/privileged/scaleio.py (function with bug is in the
  connector in this branch)
- move the test file to tests/initiator/connectors/
- modify the unit tests because the config file is accessed differently

+    Dell EMC VxFlex OS driver: This release corrects an issue where the
+    fix for `Bug #1823200 <https://bugs.launchpad.net/cinder/+bug/1823200>`_
+    did not run correctly when using Python 2.7.  If you are interested
+    in this release because of `OSSN-0086
+    <https://wiki.openstack.org/wiki/OSSN/OSSN-0086>`_, be aware that
+    you must also deploy a configuration file on compute nodes, cinder
+    nodes, and anywhere you would perform a volume attachment in your
+    deployment.  Please see the release notes for the previous release
+    for details.

+    This release corrects a problem with the fix for `Bug #1823200

+    be impacted by this bug.  If you are not using Dell EMC VxFlex OS
+    (ScaleIO) Storage as a backend for Cinder, you do not need to upgrade
