Title: Added gaufrette support

I create gaufrette storage adapter and rewrite some url-specific methods.
In mappings we configure uri_prefix for url generation and gaufrette upload_id.

```
knp_gaufrette:
adapters:
product_adapter:
local:
directory: %kernel.root_dir%/../web/images/products

filesystems:
product_image_fs:
adapter: product_adapter

vich_uploader:
db_driver: orm
mappings:
product_image:
uri_prefix: /images/products
upload_id: product_image_fs

```
