commit bd7d991309ea2bea5d175cb1f2710519936fd0c2 Author: Stephen Finucane <[email protected]> Date: Tue Aug 28 17:01:07 2018 +0100 Don't use '_TransactionContextManager._async' In commit 2d532963, all instances of 'async' were replaced with 'async_' in preparation for Python 3.7. However, one of these should not have been changed as it refers to an oslo.db object attribute. That attribute has actually been renamed itself but that rename is only present from oslo.db 4.40.0 [1]. Thankfully, an alias to the older name is provided so we use that.
