Description

STR:

• Install a stack, such as HDP 2.3
• Modify the cluster-env/stack_features structure
• Upgrade to HDP 2.6

The auto-merge which happens can't properly merge cluster-env/stack_features since it has deviated from the stock values of HDP 2.3. This is dangerous since this is needed for proper operation.

Because it's defined as a read-only value, we should be able to detect this in the auto-merge fro the upgrade and force it to the new stack's default value...
