Subject: executor: rework cgroups support

Turns out creating a cgroup per test is too expensive.
Moreover, it leads to hanged tasks as cgroup destruction
is asynchronous and overloads kernel work queues.

Create only a single cgroup per proc, but restrict
descriptions to mess with that single group,
instead test processes create own nested cgroups for messing.
