"""Building blocks shared by the CKAD task banks written for the per-task hosts (77 onwards): bash
for setups and checks. The generic ones - NET, PODS, PY - are sim/bank.py's.

The two rules of the CKS banks hold here as well: a task scores nothing before anyone has worked
on it, and what can be tested for real - a request, a file in a container, a container's
environment - is tested for real rather than read off the object.
