>
> Let's 
> * implement CatalogManager methods that will validate and save catalog changes to the MetaStorage.
> * implement Metastorage WatchListener that will apply these changes and update CatalogService state.
> Storing catalog snapshot may be ineffective as we may need to calculate a diff between old and new catalog version for further event triggering purpose. But we may save a while descriptors with some meta about the operation.
> Note: Let's make these changes aside to avoid breaking the current implementation.
