Modifies the import to actually happen when API() is called instead of when the module is loaded. This is necessary because CONF.volume_api_class is always evaluated as the default value since the config file hadn't been parsed yet when the module is loaded. Nova fixed this problem a while ago for the compute driver in https://review.openstack.org/#/c/14353/. Change-Id: I4c3d6b4300298ad0ac4e40a7a1a815cbf88bb151 Closes-Bug: #1543219
