    Aceept option to delete all associated resources
    
    Upstream commit 71e9ea4a549450dda09c34a95a8911d566821046
    There is a difference from the upstream where by default all resources are deleted
    with the stack. For Darga we will only delete resources when the flag is on.

Dan,
Assigning to you. We need to upgrade the armrest gem for 5.6.
You can assign it back to me when it is done. I'll add comment how to enable this feature.

Bill, https://github.com/ManageIQ/manageiq/pull/13311 was merged. Back over to you!

For backward compatibility purpose the delete VMs at stack retirement feature is enabled by default only for product >= 5.8.

To manually turn on the feature for users on V5.6 the automate script needs a change as following:

Cloud/Orchestration/Retirement/Statemachines/Methods/remove_from_provider

change
stack.raw_delete_stack
to
stack.raw_delete_stack(true)

Note: above change can be applied for Azure stacks only. 

Need documentation update.
