api: 3 healthcheck will fail if it relies on certs

[pirog]

for api: 3 services healthchecks run on post-start-2 and cert refreshing happens on post-start-9999 so if your healthcheck relies on the certs the healthcheck will fail: eg curl -I https://localhost vs curl -I http://localhost.

given that api: 3 services are going away this might not be worth addressing or at least not nowish especially since generally a non-cert based healthcheck is usually available,
