DEV-17835: Remove wsrep-sst-method=xtrabackup
The use of the xtrabackup and xtrabackup-v2 methods for SST has been declared obsolete since version 10.2, now it cannot be used because of the different redo log format. Accordingly, we need to remove the xtrabackup-related scripts and dynamically replace the call to xtrabackup[-v2] to the mariabackup (with a corresponding warning in the log) when the server performs SST. https://jira.mariadb.org/browse/MDEV-17835
