Cleaning up nginx conf

[rahul286]

folder - nginx/conf
we need to clean it up keeping v4 structure in mind.

• cleanup global nginx.conf at nginx/conf/ nginx.confin the repo. /usr/local/openresty/nginx/conf/nginx.conf inside container
• nginx.conf will include site specific config from /var/www/conf/nginx/site.conf. EEv4 will create/generate this file.

Users can create additional conf files in /var/www/conf/nginx/custom/ with .conf extension. Something like /var/www/conf/nginx/custom/redirects.conf.
