Description:

Added required inotify-tools to dependencies, and required files to make autoreload work, same as in SWAG.

Benefits of this PR and context:

Closes #112

How Has This Been Tested?

docker build -t nginxtest .
docker run -e NGINX_AUTORELOAD=true -d --rm --name lsionginxtest nginxtest
docker exec lsionginxtest touch /config/nginx/test.conf

Inspected docker logs lsionginxtest afterwards:

/config/nginx/ CREATE test.conf
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
Changes to nginx config detected and the changes are valid, reloading nginx
