Get index progress in SQL 2004 and above

Copy from answer from Solomon Rutzky on topic SQL Server : HOw To trace progress of Create index command. This query is very useful to trace the progress. Pam Lahoud also mention in SQL 2019, that is new dmv called sys.index_resumable_operations  which trace resume index operation.
