Forward the requests to another endpoint and include a delay in response.

docker run -p 8888:8888 -d raittes/lag-api -proxy http://httpbin.org -lag 500ms

Test:

curl -w "\n%{time_total}\n" localhost:8888/ip
curl -w "\n%{time_total}\n" localhost:8888/user-agent
curl -w "\n%{time_total}\n" localhost:8888/headers
