Dataset-based MetadataStorage should not depend on dataset framework

Description

The MetadataDataset is a known entity, and we don't need to use the dataset framework to create or instantiate it. Also, the datasets should be created when the metadata service (or the master) starts, instead of calling getOrCreate() at runtime.

Similar to the nosql version of StructuredTable.
