swarm/api: integrate tags to count chunks being split and stored
swarm/api/http: integrate tags in middleware for HTTP `POST` calls and assert chunks being calculated and counted correctly
swarm: remove deprecated and unused code, add swarm hash to DoneSplit signature, remove calls to the api client from the http package
