Update ESXi template

[rmamba]

ESXi does not set any expiration and compression on the resources so we force it with nginx to improve performance

location ~* \.(js|css|png|jpg|jpeg|gif|svg|ico)$ {
 expires 30d;
 add_header Cache-Control "public, no-transform";
		proxy_pass https://esxi-3;
gzip on;
gzip_vary on;
gzip_min_length 10240;
gzip_proxied expired no-cache no-store private auth;
gzip_types text/plain text/css text/xml text/javascript application/x-javascript application/xml;
gzip_disable "MSIE [1-6]\.";

}
