Change I01b22593724616bc0a7793c509ecabf095d6927d made the live_migrate() method in the ServerManager conditional on the API version requested. This broke the host-evacuate-live command which is calling ServerManager.live_migrate() directly with one too many arguments for the v2.25 version of the method. This updates the host-evacuate-live shell to behave like the live-migration method and be aware of the API version when calling the live_migrate() method. Related to blueprint making-live-migration-api-friendly Change-Id: I4dbeb6ebe03f03799b706be2d787d21484b5c664 Closes-Bug: #1561938
