This commit restores defaults and functionality regarding binlogs to the way it was prior to MDEV-27524. The mariabackup utility no longer saves binlogs files as part of a backup without the --galera-info option. However, since we use --galera-info during SST, the behavior of mariabackup changes and, in combination with GTIDs support enabled, mariabackup transfers one (most recent) binlog file obtained after FLUSH BINARY LOGS. In other cases, binlogs are not transferred during SST in mariabackup mode. As for SST in the rsync mode, it works the same way as before MDEV-27524 - by default it transfers one last binlog file. The --sst-max-binlogs option for mariabackup and the sst_max_binlogs parameter in the [sst] / server sections are no longer supported for SST via mariabackup.
