After iterating on the GRPC API, the changes required for the actual implementation are now included in the content store. The begin change is the move to a single, atomic `Ingester.Writer` method for locking content ingestion on a key. From this, comes several new interface definitions. The main benefit here is the clarification between `Status` and `Info` that came out of the GPRC API. `Status` tells the status of a write, whereas `Info` is for querying metadata about various blobs.
