I encountered a situation where the console - I am running usally at debug level 2 or 3
is flooded with HTTP 400 (which are kind of annoying):
```
[15:02:41] [DEBUG] got HTTP error code: 400 (Bad Request)
[15:02:41] [DEBUG] got HTTP error code: 400 (Bad Request)
[15:02:42] [DEBUG] got HTTP error code: 400 (Bad Request)
[15:02:42] [DEBUG] got HTTP error code: 400 (Bad Request)
[15:02:42] [DEBUG] got HTTP error code: 400 (Bad Request)

[15:02:46] [DEBUG] got HTTP error code: 400 (Bad Request)
[15:02:46] [DEBUG] got HTTP error code: 400 (Bad Request)
[15:02:46] [DEBUG] got HTTP error code: 400 (Bad Request)
[15:02:47] [DEBUG] got HTTP error code: 400 (Bad Request)
[15:02:47] [DEBUG] got HTTP error code: 400 (Bad Request)
[15:02:48] [DEBUG] got HTTP error code: 400 (Bad Request)
[15:02:52] [DEBUG] got HTTP error code: 400 (Bad Request)
```
as this is triggered by almost every request.
This is a workaround for the above scenario so that on the console I see only what I wanted
to, like:
```

```
Admittedly this is may seem a bit hackish as it only addresses HTTP 400 and doesn't cover other
app specific errors which can happen in other scenarios. It could also be that ``--suppress-400``
would sound better as it would describe better what it does but as there's
``--ignore-401`` so I settled for ``--ignore-400``.
