Brian Rosmaita b58ac2894b Drop cinder v2 API support
Cinder v2 API is deprecated since pike release. Along with the removal
of cinder v2 API support in cinderclient (change I335db5c1799e drops
v2 support), this commit drops cinder v2 support in horizon.

The next release of python-cinderclient drops v2 support,
so horizon needs to use v3 classes.

Includes a workaround in unit tests for two cinderclient.v3 classes
that are missing in the cinderclient releases prior to 8.0.0.  The
workaround can be removed once cinderclient change I335db5c1799edb2
is merged and released.

With this release, Horizon uses only the Block Storage API v3.
Horizon has been using the Block Storage API v3 by default since
Queens, so this change should not impact Horizon functionality.
(The Block Storage API v2 was deprecated by the Cinder project
in the Pike release, and is scheduled to be removed in the Xena
release.)
