The logic for this is in src/core/cgroup.c's cgroup_context_get_mask()
call, which will determine to which cgroup controllers to add a unit
to. Note that setting MemoryLimit= will not actually propagate to the
boolean exposed in MemoryAccounting=, it will just have the same effect
as if it was set...
