[Bug 1828442] CVE-2020-10997 percona-xtrabackup: Information exposure via cmd line output and table history

Percona XtraBackup before 2.4.20 unintentionally writes the command line to any resulting backup file output. This may include sensitive arguments passed at run time. In addition, when –history is passed at run time, this command line is also written to the PERCONA_SCHEMA.xtrabackup_history table.
