Parent Group Merge Algorithm

The parent group merge algorithm enables the system to merge policies that contain
references to parent groups and create an internal parent group for each internal
parent group in a component policy in the final merged policy. There is a one-to-one
correspondence between an internal parent group in the merged policy and an
internal parent group in a component policy.
NOTE: The naive parent group merging algorithm is not compatible with this parent
group merge algorithm. If you have service definitions that used the naive parent
group algorithm, you need to modify those service definitions to work with this
algorithm.
