There is a small amount of client side work needed to expose the new view etags for PLFM-4249.
There is a new parameter in org.sagebionetworks.repo.model.table.Query called 'includeEntityEtag'. When 'includeEntityEtag' is set to true, the query results for a view will return a List<EntityRow> (when false a List<Row> is returned). This new EntityRow extends Row and includes an Etag.
There is also a new parameter in org.sagebionetworks.repo.model.table.DownloadFromTableRequest called 'includeEntityEtag'. When 'includeEntityEtag' is set to true for a CSV download a new column will be included in the CSV called ROW_ETAG.
There is a new parameter in org.sagebionetworks.repo.model.table.PartialRow called 'etag'. When a client creates a PartialRow to update a view, the etag should be copied from the EtntityRow to the PartialRow.
