 In #33232, we make chutney check for relay and bridge descriptors, and
 relays in the consensus, before verifying. But we don't check for relay
 microdescriptors.

 The easiest way to check for relay microdescriptors, is using each relay's
 ed25519 key. In #30642, we will add an `ed25519-identity` file to each
 relay's data directory. Chutney can read the contents of this file, and
 then search for it in `cached-microdescriptors` and `cached-
 microdescriptors.new`.
