MDEV-22659: Create one single unified and optimal logrotate config
Replace mysql-log-rotate.sh and debian/...mysql-server.logrotate with one new unified and well documented version. Name is mariadb.logrotate.in as in 10.11 branch onward we use now the 'mariadb' name, and use 'logrotate' to match the actual name of the utility. Also automatically disable deprecated /etc/logrotate.d/mysql-server file on deb upgrades. Reviewer: Daniel Black Reviewer edits made: * Added 'su mysql mysql' to the logrotate this is more RPM friendly. This is commented on Debian * /var/log/mysql is the path on SuSe based distributions
