Access denied to application on Deploy Stage without application WRITE permissions

Issue

Currently, application WRITE permissions are required to use the Deploy Stage in Spinnaker with AWS, GCP, Titus and other deployment targets.However, when using the Kubernetes provider, only EXECUTE permissions are needed to use the Deploy Stage.This is an open issue in OSS Spinnaker: spinnaker/spinnaker#6400EXECUTE application permissions were developed recently and, so far, have only been fully implemented on the Kubernetes V2 provider. It is possible to set EXECUTE permissions on the Deploy Stage for other targets, however the stage will also require application WRITE permissions to run successfully.

Cause

Deploy stage on** targets other than the Kubernetes provider** does not run successfully because it does not have application WRITE permissions set.
