In order to restore logical backups to a GTID enabled MySQL instance,
mysqlpump must do two things to ensure that the GTID metadata on the new
instance matches that of the original when the backup was taken
1. Disable binary logging.
2. Set @@GLOBAL.GTID_PURGED=@@GLOBAL.GTID_EXECUTED

Prior to this patch mysqlpump was not performing the above 2 steps. Now this
patch fixes the same.
