Resources which go into an unknown or error state currently raise an Error exception. There are cases where Error is too generic to make decisions on, so 2 new exceptions have been created: * ResourceInError: raised when a resource goes to a status which is known to represent an error for that resource * ResourceUnknownStatus: raised when a resource goes to a status which heat is not aware of. If ResourceUnknownStatus is ever raised then this is a heat bug, since this is a status which heat is not aware of. Any resource which go into an in-progress state has been updated to raise ResourceInError and ResourceUnknownStatus where appropriate. Change-Id: Ied83b030d30b8c26d9f4a1e454c71cd30715b0ba
