Allow include of extra Nginx configuration files to provide extra paths (i.e. health check paths)

Content & configuration

OpenApiSpec is not relevant for this feature request. The only thing that is relevant, is the nginx.conf

Is your feature request related to a problem?

I'm unable to configure extra locations, such as health checks for the swaggerapi/swagger-ui Docker image.

Describe the solution you'd like

Add the following to the server section of nginx.conf:

server {
    ...
    include /etc/nginx/config.d/*.conf;
    ...
}

This allows for extra configurations to be provided by the user. Hence, it will also prevent path clashes, as that would be the responsibility of the user.

Describe alternatives you've considered

I'm currently overwriting the nginx.conf, as there's no other way for me provide extra locations.

Start by reading docker/nginx.conf, focusing on its server section and the existing configuration layout. Add support for including user-provided files from /etc/nginx/config.d/*.conf, then verify that the Docker image can provide extra locations such as health check paths without replacing nginx.conf.
