Prior to 97f33bb1537d04905cb84199672bcdf46ebb4e65, executor cgroup validation errors were
silently ignored. Enforcing them reveals test cases that missed them.
This doesn't change customer facing contract, as resource struct is
is either configured or we default to 100 (much higher than 2).
this allows us to drop a cyclical import, but is subobptimal as it
requires BaseDriver tests to move. This falls firmly into the realm of
being a hack. Alternatives welcome.
