MDEV-17058: Test failure on wsrep.variables MDEV-17060: Test failure on galera.galera_var_slave_threads Fix incorrect calculation of increased applier (slave) threads. Note that increase change takes effect "immediately" but we should use proper wait condition to wait it. Reducing the number of slave threads is not immediate as thread will only exit after a replication event.
