Trolli Schmittlauch f15d83baff Refactor predecessors and successors to hold RemoteNodeStates
- neighbour nodes need to be contacted reliably
- Only holding NodeIDs requires a cache lookup for getting hostname and
  port. This is brittle as the entry could've been purged from cache.
- refactored ASN.1 scheme, types and add/ sort/ remove implementations
