Instrumentation of Phoenix requests
To integrate Appsignal with Phoenix, *use* the `Appsignal.Phoenix` module in
your `endpoint.ex` file, just before your router:
```
use Appsignal.Phoenix
```
This will install a plug which measures request time, and also will
trap common HTTP errors (like 4xx status codes).
