Add context to all (non-trivial) calls to the storage layer. Contexts are propagated through the REST client. - `context.TODO()` is left in place for the places where it needs to be added to the caller. - `endWalkCh` could probably be removed from the walkers, but no changes so far. The "dangerous" part is that now a caller disconnecting *will* propagate down, so a "delete" operation will now be interrupted. In some cases we might want to disconnect this functionality so the operation completes if it has started, leaving the system in a cleaner state.
