Label SMB Reads with metadata about SortedBucketIO class

[clairemcginty]

It would be helpful if SMB read transforms were labeled with info about their component read types (Avro, Parquet, etc)

Proposal: Make the BucketedInput abstract class extend HasDisplayData and have all typed SortedBucketIO.Read/SortedBucketIO.Transform builders implement it with relevant info (i.e for AvroSortedBucketIO, include schema name/generic|specific, input path, etc). Then SortedBucketSource/SortedBucketTransform can append it to their transform labels here.
