Describe the issue
We might want to reduce the builder capacity in koji for the s390x builders from 4 to 2. AFAIK the practice is to have the capacity to match the number of CPUs on the builder and the s390x ones have only 2 CPUs configured.

When do you need this? (YYYY/MM/DD)
soon

When is this no longer needed or useful? (YYYY/MM/DD)
N/A

If we cannot complete your request, what is the impact?
Potentially overloaded builders.
