[User-Story] Seperate signing module

[Eknir]

Rationale

The Swarm codebase currently requires private keys to be stored on disk, in order to interact with Swarm. This approach has obviously security problems and is not very flexible. We want to enable the usage of a separate signing module.

User-Story

As a user of Swarm, I want to be able to interact with Swarm, without the need to store private keys on my node.
