Make entity config & state available through same RBAC rule

[jamesdphillips]

• Updates entity configuration & state resources to make them available through the existing "entities" RBAC rule.
• Previously the corev3 package machinery produces a test to verify that all the types in the package had a unique RBAC name, and barring any Chesterton fence scenarios, I've skipped these tests for now. The previous behaviour seems overzealous as multiple types with the same RBAC rule seems reasonable to moi.
• I've tried to update any places that depend on RBAC name uniqueness but may have missed something!
