Ingest description from (confluent) kafka schema registries

Is your feature request related to a problem? Please describe.

Datahub supports the ingestion of kafka streams with AVRO schema: https://datahubproject.io/docs/generated/ingestion/sources/kafka/

Currently the field names and datatypes are imported from the schema registry, but the description is not.

Describe the solution you'd like

It would be nice if the description would be imported as well.

Describe alternatives you've considered

You can still manually add the description, but it would be more complete if it was there.
