This removes the ability to configure which cgroup controllers to mount together. Instead, we'll now hardcode that "cpu" and "cpuacct" are mounted together as well as "net_cls" and "net_prio". The concept of mounting controllers together has no future as it does not exist to cgroupsv2. Moreover, the current logic is systematically broken, as revealed by the discussions in #10507. Also, we surveyed Red Hat customers and couldn't find a single user of the concept (which isn't particularly surprising, as it is broken...) This reduced the (already way too complex) cgroup handling for us, since we now know whenever we make a change to a cgroup for one controller to which other controllers it applies.
