In order to use properties defined on a foreign repo, we need to access property info (like the data type). For this, we need to define and implement a service that can fetch information from different repositories.

This needs tree steps:

• Factor the PropertyInfoStore::getXxx methods into a read-only service interface , PropertyInfoLookup
• Implement a per-repo dispatching version of PropertyInfoLookup, similar to DispatchingTermBuffer or DispatchingEntityRevisionLookup.
• Make PropertyInfoTable repo-aware (just check the repo name, like WikiPageEntityMetaDataLookup does)
