[tools] KUDU-1945: Kudu table copy and perf loadgen
This patch introduces support for 'table copy' CLI tool for the tables with auto-incrementing columns. While scanning the source table, we do not scan the auto incrementing column and while writing back the rows to the destination table, we write all the scanned rows. The auto-incrementing column is then populated at the server side during each row's write. It also adds support for 'perf loadgen' CLI tool to insert into tables with auto incrementing columns. This currently only works with insert and insert_ignore write operation. upsert and upsert_ignore are not supported currently.
