* Consolidate various duplicate docs to the main entry point. Especially the duplication that followed after ExternalStoreFactory and ExternalStoreAccess were introduced with ExternalStore left as deprecated wrapper. * Officially mark ExternalStoreFactory as internal, pointing to ExternalStoreAccess instead. And document why the latter exists, since it seems all its methods could trivially move to the factory class. Follows-up I40c3b553, where it was explained that the factory is meant to be an internal implementation detail, with the access class meant to resemble ExternalStoreMedium. * Use consistent terms for "protocol", "location" and "object" (reduce use of words like medium, backend, type, blob, revision, etc. within this code). * Document that ExternalStore is fundamentally designed as an append-only store (per T247383). Bug: T247383 Change-Id: I1094af7d35a14f9e47b8791f3e4cc888e8cbfc7f
