Rework logic for setting threads in my.cnf
This patch updates logic for setting the following parameters
* innodb_read_io_threads
* innodb_write_io_threads
* wsrep_slave_threads
When they are set to 0 (default value) number of threads will be
calcullated dynamically based on number of CPU cores but not higher
than 12.
Default number for paralell percona backups is decreased to 1.
