Enhance Subscription Request Response with outsideSubscriptionBoundary Property

[DutchBen]

Description: As a frontend developer tasked with implementing the functionality described in ticket workfloworchestrator/orchestrator-ui-library#367, I propose an enhancement to the subscription request response. Currently, when a subscription is requested, the return value includes productBlockInstances. To better facilitate frontend development and provide more context, I suggest adding a new property to each productBlockInstances object: outsideSubscriptionBoundary.

Details:

• Property Name: outsideSubscriptionBoundary
• Type: Boolean
• Purpose: This property will indicate whether the associated productBlockInstance is outside the subscription boundary.
• Usage: Frontend developers can utilize this property to adjust the display or behavior of elements based on their placement relative to the subscription boundary.

By adding this property, we can streamline frontend development and enhance the user experience by providing valuable information about the subscription boundary directly within the response data.
