Create parameter for disabling aio_write

[fabiorauber]

In certain situations (like when enabling cache on the Ingress Nginx instance) it would be beneficial to have an option to disable aio_write in the Nginx configuration. I've stumbled upon an issue with stalled cache files that do not get updated until you restart Nginx (https://trac.nginx.org/nginx/ticket/2162), and the recommended workaround was to disable aio_write.

Unfortunately, to achieve this right now, it is necessary to customize the Nginx configuration template. Being just a feature flag, it would be easier if the Nginx Ingress Controller had an option to disable it.

ingress-nginx/rootfs/etc/nginx/template/nginx.tmpl

aio_write on;
