Salvatore Orlando ff837025e9 Fix bulk create operations and make them atomic.
Bug 1024844
Bug 1020639

The API layer is now able to issue bulk create requests to the plugin,
assuming that the plugin supports them. Otherwise, the API layer will
emulate atomic behavior.
This patch also implements OVS plugin support for bulk requests.
