Launches a new Application or Job instance, returning an Instance and Task ID. The Task ID should be used against the /task endpoint to determine the availability of the the running instance.

Instance behaviour is controlled using the specification. You will need to consult individual applications to determine what can be placed in the specification. Applications typically provide a template describing its options.

An Application instance is not Ready for use until the corresponding TaskState is STARTED.

A Job instance typically runs to completion, reaching the TaskState SUCCESS when successful and FAILURE is unsuccessful.
