aws-proofs: provide optional NUM_DOMAINS override

If the NUM_DOMAINS input is set, the proof build system will override the KernelNumDomains setting. We make the NUM_DOMAINS value part of the cache key so that we get fast proofs on master for things that already had a successful test on a pull request.
