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. Change-Id: I515148d870d0dff8371862fe577c477538364929
