Struct CollectionGroupId 

pub struct CollectionGroupId(/* private fields */);

Stable identity for the collection group that one Placement Authority owns.

A group is the control-plane sharding unit for placement decisions. Related collections can share a group so they stay in one authority domain; a large collection can instead be the group’s only member when it needs isolated placement policy.
