swarm/api: refactor and improve HTTP API (#3773)

This PR deprecates the file related RPC calls in favour of an improved HTTP API. The main aim is to expose a simple to use API which can be consumed by thin clients (e.g. curl and HTML forms) without the need for complex logic (e.g. manipulating prefix trie manifests).
