Added non-breaking db implementation specific settings support to collection definition.

"repositorySettings" object can now be added to the collection definition containing specific settings per implementation. If the implementation is used those are passed to the repository via extend. How and if those settings are used depends on the viewmodel db implementation.

d.defineCollection({
   name: "col",
   repositorySettings: {
     elasticsearch: {
        // specific elasticsearch settings
     },
     mongodb: {
        // specific mongodb settings
     }
   }
});
