UI - Custom timeouts setup

[renanmedina]

Related to: #257

I also needed this feature to make it faster to setup multiple proxies without the need for the custom configuration in all of them.

I heavily use Nginx Proxy Manager, and even though creating custom rules are easy enough, having the option directly in the UI makes life easier and setups faster.

Maybe the best way would actually to have a "Timeouts" tab instead of just putting it directly into advanced tab??
