Report relays that sbws sees in the consensus, but never chooses to test
We should count:
- the number of consensuses that sbws has seen a relay in the consensus
- the number of times sbws chooses to test a relay
- the number of times sbws chooses to exclude a relay (for example, because it's an authority)
If there are a large number of exclusions, we should split the exclusions into subcategories.
