cmd-exec payload should be payload, not err msg.
Issue-ID: CCSDK-2549 fixes: 1. CMD-exec returns payload as JSON object. There was some regression where we overwrite returned JSON with errMsg. 2. adds 100ms delta to executionTimeout, as was in our downstream version (want to guarantee that we get grpc timeout exception on BP side rather than coroutine w/o waiting extra) 3. setNodeOutputErrors should not have ability to set execution status to success. rev1. initial import rev2. reworked the calls to setNodeOutputErrors: addError was brought out of it as we can set the node execution error based on prepare.env or execution. rev3. did not mean to add BlueprintRuntimeService change Signed-off-by: Oleg Mitsura <oleg.mitsura@amdocs.com> Change-Id: I6d509df5ae51598f33ab9f0ea53806d653cf79c0
