qa/suites/*/rados_cls_all.yaml: load all classes

qa/suites/*/rados_cls_all.yaml: load all classes

the intention to add the whitelist was to test "sdk" class, but if we
add new classes to the list, and add tests exercising them, the tests
fail if we fail to update these `rados_cls_all.yaml` accordingly.

so in this change, the list is now '*' which allows OSD to load all
classes found in the specified directory
