add CORS support

[scotthelm]

Conditionally adds CORS support to a container's nginx config The condition is based on a container's CORS_ENABLED environment variable. The default value is false, meaning that the existing behavior will not change if the environment variable is missing.

e.g.

// docker-compose.yml ... services: web: environment:

• CORS_ENABLED=true

would enable CORS for that container's nginx config
