Review comment:
commit 230ee36b9147a11d7ce299aa9fcbb590324faf68
Added the authorizeByResourceType() API to the benchmark and simulate the
worst case: every allow ACL on the same resource has a dominant deny ACL.
Adjust the `resourceCount` parameter to "10000", "40000", "80000" since each
cluster is unlikely to have more than 10k resources. Also, since we are testing
against the worst case mentioned above, I think the "10000" cases are adequate
for us.
