Managing files from AWS s3

[Libisch]

Overview

Images scraped using Scrapy (from Bagnowka for example) are uploaded to AWS s3, not to google storage (were all the photos are currently stored). Even though the correct main_image_url is specified.
in /bhs_api/item.py:

def get_image_url(image_id, bucket):
    return  'https://storage.googleapis.com/{}/{}.jpg'.format(bucket, image_id)

Expected

The main image url should not be referring to gcs if other storage is specified inmain_image_url.

"main_image_url": "https://s3-us-west-2.amazonaws.com/bagnowka-scraped/full/95eb0e2ccf2a62ad46939994718ba150.jpg"

Actual

The API returns PictureId appended to the storage.googleapis uri:

"main_image_url": "https://storage.googleapis.com/bhs-flat-pics/95eb0e2ccf2a62ad46939994718ba150.jpg"

@Libisch following our discussion -

1. bagnowka items should have some kind of indication that we should use their url attribute as-is
2. item.py enrich_item function should check this attribute

Done. see #165

@Libisch if it's done, please assigne to @TheGrandVizier for QA (if needed)
if it doesn't require QA or it's very technical you should assign to yourself for QA
