Andrey Mashenkov updated IGNITE-19080:
--------------------------------------
Description:
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.
