Add application name to "No Application Configured" and "Application Not Responding" error messages

[msabramo]

When tsuru doesn't recognize the application you're trying to hit, you get:

No Application Configured

This domain is not associated with an application.

In ordinary usage, I guess the application name would be obvious from what you just typed in the URL.

However, I have a set up where am I going through a reverse proxy so the application name is inside an nginx configuration file and thus not immediately obvious to the user.

E.g.: I type http://foobar.mycompany.com/myapp and that hits an nginx that routes to a tsuru application called "myapp".

This may not be possible to fix in tsuru because these errors come from hipache -- e.g.:

• https://github.com/hipache/hipache/blob/master/static/error_400.html

Unless hipache allows customizing the error pages?

[msabramo]

The Hipache docs at https://github.com/hipache/hipache say:

When something wrong happens (e.g., a backend times out), or when a request for an undefined virtual host comes in, Hipache will display an error page. Those error pages can be customized, and a configuration parameter is available to specify where these custom pages are located.

[msabramo]

Here's how to configure custom error pages:

• server.staticDir: The absolute path of the directory containing your custom static error pages. Default value null means it uses Hipache's pages.

From hipache/hipache@c3fef07

These seem to be static pages though so it still looks difficult if not impossible to include the application name unless each tsuru application gets its own directory of static error pages.

I'm poking around with changing hipache to do what I want:
