Subscription Creation: Fixes for code review after demo

- Change missleading subscription details in testware
- Change datastore check to comply with CPS enum
- Remove redundant CloudConstructionException
- Change exception handling in cloud event mappers
  to avoid loss of information
- Remove exception handling from scheduler service
  as discussed in the meeting

Issue-ID: CPS-1732
Change-Id: I9fee2eafd4db97a0eed80e39219463c904f5a980
