I saw that support for SSL bundles was added to the actuator info and health endpoints in #41205 and I think it would be really helpful to make that information available in the metrics endpoint as well. I would like to utilize this enhancement to set up an alarm in my monitoring software so that I can renew my certificates before they expire.

I would imagine something like this:

GET http://localhost:8080/actuator/metrics/ssl.bundle.expiry { "name": "ssl.bundle.expiry", "baseUnit": "days", "measurements": [ { "statistic": "VALUE", "value": 351.0 } ], "availableTags": [ { "tag": "cert_alias", "values": [ "my-alias" ] }, { "tag": "bundle_name", "values": [ "mybundle" ] } ] }
