Support for graceful server shutdown under Kubernetes termination life-cycle.
The plug supports a /__traffic endpoint which normally returns 200. When the VM
receives a SIGTERM signal, the endpoint starts returning HTTP error code 500,
which, when used with an HTTP readinessProbe, ensures that traffic is routed away
from the pod, before a delayed graceful shutdown begins.
See modules for detailed documentation, also my blog post, Graceful shutdown on Kubernetes with signals & Erlang OTP 20.
