Certificate inventory: names, issuers and expiry dates

One row per certified hostname with how many certificates it has had, when the name first and last appeared in a log, every issuing authority and when the newest certificate expires. Useful for spotting shadow IT, rogue issuers and certificates about to lapse across a portfolio of domains.
