[operations/docker-images/production-images@master] envoy: Add draining script and configuration

Mentioned in SAL (#wikimedia-operations) [2023-06-06T09:11:07Z] <claime> Building production images - T338014

Setting the following environment variables now controls envoy's draining behaviour:
DRAIN_TIME_S
DRAIN_STRATEGY

In case a non-default admin port is used, the ADMIN_PORT environment variable has to be set for the drain-envoy.sh script to work.
