internal/https: add health checking support and use it

CL 454935 broke the Kubernetes ingress by requiring IAP on health
checks. Move /healthz handling into internal/https, where it
automatically bypasses authentication and removes some duplicate trivial
implementations.

Unfortunately, GKE is not capable of inferring health check parameters
from a multi-container pod like relui, so we have to change our
BackendConfig. That sets off a yak shave -- I made the questionable
decision to use the same backend for all our IAP services, and the
coordinator doesn't currently support /healthz. Split all them up and
delete the devapp configuration I was using for testing way back in the
day.
