[sdk] Request to release new version of openstacksdk to fix connection leak

Hi, I reported a bug in openstacksdk [1] that is affecting Senlin. It appears that the latest openstacksdk code in master branch contains a fix for that bug. Is it possible to cut a new openstacksdk release based off master for Stein? Thanks, Duc [1]: https://storyboard.openstack.org/#!/story/2005306
