Package healthcheck helps you implement liveness and readiness checks
for your application. It supports synchronous and asynchronous (background)
checks. It can optionally report each check's status as a set of Prometheus
gauge metrics for cluster-wide monitoring and alerting.

It also includes a small library of generic checks for DNS, TCP, and HTTP
reachability as well as Goroutine usage.
