Code Issues Proposed changes

use context manager from neutron-lib

Browse Source 
Access to neutron.db.api's context manager is already in neutron-lib
and in fact neutron is already using it as a shim. This patch switches
over context manager access to use neutron-lib's accessors.
Also see https://review.openstack.org/#/c/613122
