Currently, we're doing "sync" in databroker server. If we're going to support multiple databroker servers instance, this mechanism won't work. This commit moves the "sync" to storage backend, by adding new Watch method. The Watch method will return a channel for the caller. Everytime something happens inside the storage, we notify the caller by sending a message to this channel.
