Refactor Needles Interfaces and Rename "process" to "backend"

Reason:
- Interfaces with a single method can be replaced with
  interfaces from java.util.function.
- Less interfaces = less code = less maintenance!
- Spring can inject beans by name so we name dependencies correctly
  to prevent ambiguity.

Others:
- Rename process to backend since backend gives a better description
  of its components.
