Change subject: Introduce HashSiteLinkStore ...................................................................... Introduce HashSiteLinkStore separating and refactoring some of the code in MockRepository that implemented SiteLinkLookup. also have MockRepository use that instead of all the implementation there. separating this and having a standalone implementation is useful in cases where we just want a SiteLinkStore or SiteLinkLookup. at the moment, HashSiteLinkStore is covered indirectly by MockRepositoryTest, but in a follow-up patch, shall separate the tests, as well and see where we can use HaskSiteLinkStore directly in tests instead of MockRepository (as a SiteLinkLookup).
