A stub to allow clients to do synchronous rpc calls to service Datastore.
Each RPC normalizes the partition IDs of the keys in its input entities,
and always returns entities with keys with normalized partition IDs.
This applies to all keys and entities, including those in values, except keys
with both an empty path and an empty or unset partition ID. Normalization of
input keys sets the project ID (if not already set) to the project ID from
the request.
