Added engine_name parameter to action creation.
With implementation of new engines (nova, rsync, ...) a regression was introduced - user is no longer able to create working action for nova instance backup because config generated by freezer-scheduler passed to freezer-agent doesn't contain 'engine_name' thus falling back to default value 'tar' even when 'mode' is set to 'nova'. This patch adds possibility to specify 'engine_name' in web UI which is then passed to freezer-scheduler job cfg. Change-Id: Ifc4ed728db369da54fecef3c2ecf4dfcbfe4fefb
