Add "finalOutcome" flag to OperationOutcome
The Actor clients receive notifications of operation failures, but no indication if it's the final failure, thus they do not know if they should progress on to the "failure" policies. Issue-ID: POLICY-2385 Signed-off-by: Jim Hahn <jrh3@att.com> Change-Id: If053ed459e1d790e58eca950a8feeabaf4d67a41
