docker healtheck not working when NGINX port has been changed

[Emil Bostijancic]

steps:

• start docker container with env variable HTTP_PORT=8080

expected result:

• container is healthy and started

actual:

• container stays in starting state and does not migrate to healthy state

the reason is that the healthcheck script called nginx.sh does not use the env variable HTTP_PORT in the check. It always checks for http port 80

fix #802 adjust nginx healthcheck port according to env
