Add LogisticsConfigGroup , some generalization

[kt86]

It starts with only few setting:

• path to the LSP's file location
• definition, whether the VRPs of the different carrier types (collection, main run, delivery) should be based on Services (as it is now hard-coded) or Shipments (as I plan to implement in the next step for the distribution...)

Moreover I started to make some steps of the scoring / tolling more customizable.. this will also be continued in further PRs.
