Function CreateApplicationWithRetry

pkg/cmd/shared/apputil/create.go:22–67

CreateApplicationWithRetry creates an application, retrying with a different region if the selected one has no available cluster. The optional tracker (nil-safe) records which step the flow is in, so the telemetry of the calling flow can tell where the user stopped.
