Add MetadataMap to StyleInfo Catalog objects and its Rest entpoints

Description

Most of the catalog info objects have a MetadataMap to store metadata.
StyleInfo (StyleInfoImpl) misses that.
It would be useful to add it, so that we can append metadata to styles (title, description) to be used by clients.
The metadata should be properly serialized (saved/loaded) in GS catalog and be updatable / readable by the REST APIs.
