Return outcome of procedure execution from Procedure Status API

Andrea Duò

At the moment, the Procedure execution status public API only returns the outcomes "Completed" or "Running", and when it is completed there is no detail on whether it was completed successfully or not. It is a common ask for the client application's owners to be able to detect whenever the Board procedure completed with an error, so they can at least be notified and manage the exception accordingly. Alternatively, if in the future we will have Board logs content exposed through an API, this complementary information could be maybe retrieved through a subsequent request to this new API.
