From 9f26e65c62fd5a4a1fbf9048e3bfe857b18729c9 Mon Sep 17 00:00:00 2001
From: Shobhi Jain <shobhi.jain@intel.com>
Date: Wed, 7 Feb 2018 11:08:05 +0000
Subject: Replace neutron subnet creation with shade.
Function 'create_neutron_subnet' now uses shade client
instead of neutron client.
JIRA: YARDSTICK-890
Change-Id: I8eb5295cecd73742bfb5a7d0764af6f45ef0685e
