Feature lifetime is tied to storage_service lifetime, but features are now managed by gossip. To avoid circular dependency, add a new feature_service service to manage feature lifetime. To work around the problem, the current code re-initializes features after gossip is initialized. This patch does not fix this problem; it only makes it possible to solve it by untyping features from gossip.
