Change how we namespace our attribute ids

[bzbarsky-apple]

Problem

Right now our namespacing looks like ClusterName::Ids::AttributeName. We want to have metadata about attributes other than the id, so are planning to introduce a ClusterName::AttributeName namespace anyway. And in that case we should have the ids be ClusterName::AttributeName::Id.

Change overview

Do the above renaming.

Testing

No functionality changes. Tree compiles.
