Enable plugins to create config stores for repository config

Therefore we have to
- add an API to create stores for repository ids, not only for
  repositories,
- make v1 properties available in scm-core
- make sure that properties are extracted from repositories before the
  update step of a plugin runs (this is done by sorting the update steps
  in a way so that "core" update steps are executed before plugin update
  steps with the same version)
