Support partial updates in batch API

[Pfeil]

Plan: support updates of a whole graph, which may be a mix of new and existing records.

Some guidelines:

• make API (body to sent) more explicit on what it will do
• simplify code
• For now, support only full overrides, as the typed pid maker is used to with the non-batch api. Consider if a parameter makes sense to control this somehow. Like "merge" or so.

Status

• introduce a way to express that a record may be registered already -> PidNode stores a pseudo pid (or not). Now, the PID can fully express the existence (or the wish for a custom PID).
  • Probably we should check if a PID is really registered if a request provides one to avoid expensive rollbacks on errors.
• Adjust createPIDs
• Adjust tests
