Collections are new. openstacksdk as of now doesn't support python2. We shouldn't pretend to support python2 either. If you're using ansible new enough to use collections, you can use python3. This release of openstacksdk only supports 3.6 and onwards, so set that as our min. Change-Id: I34d544ce48f25bffde8e6e0cf82cdf9a85e681c3
