Feature Request: Server's rewrite rules htaccess/ nginx configs

### What

By using Apache or Nginx we usually have the chance to manage some redirections or reverse proxy routes to internal servers or whatever configs we need to do for the server and we usually do it with the htaccess or nginx config files.

Over here I cannot find the way to do it and to fully use this as our main environment for development we need to be able to handle those kind of things.

### Why

At so many projects that I work with, we need to customize somethings like the following (which the purpose is save storage space in the local environments using the images in production or staging if the image is not available in our locals):

```

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^wp-content/uploads/(.*)$ https://www.domain.com/wp-content/uploads/$1 [R=301,L]

```

### How

Create some feature that allow us to add those rules either in htaccess format or nginx format as a file in the root of the project or somehow in the StudioUI.
