Update OCF and request repartitioning of all the IO classes when loading IO class configuration, so that data cached under the old classification rules is moved to the unclassified IO class and gets classified again according to the new rules on next access. It applies also to the IO classes that are removed from the configuration. Signed-off-by: Daniel Madej <daniel.madej@huawei.com> Signed-off-by: Robert Baldyga <robert.baldyga@unvertical.com>
By default reclassify data from all IO classes to default. With `--keep-classification` flag reclassify data only from removed IO classes. Signed-off-by: Daniel Madej <daniel.madej@huawei.com> Signed-off-by: Robert Baldyga <robert.baldyga@unvertical.com>

Leave each non-default slot empty with 50% probability, so that the generated configurations also exercise sparse IO class tables. Make ioclass stats sections tests check only configured ioclasses. Signed-off-by: Robert Baldyga <robert.baldyga@unvertical.com>
