F20: add CleanupOnFailure() to ServiceInterface
* Add to ServiceInterface a new function:
`CleanupOnFailure(states []ServiceState, executionErr error) error`
* Fill in the implementations of ServiceInterface with placeholders
This API allows to simple cleanup if execution of one of the states
fails. However, it is possible to use this API to do a Command pattern
with complete Undo() if that's feasible for the service:
States can keep all the data, necessary to undo the state.
