Task 32132
Currently, importing image requires either uploading them
one-by-one (after the initial import), scripting that upload, or
converting all images to base64 and putting that in the import
file (leading to a huge unreadable file) before actually doing the
import.
This is problematic for non-technical users, especially when they're
deploying or synchronising e-commerce products.
This change matches URLs in image fields and goes to read the URL &
load that as image data. It performs the read inline which is reactive
but means the imports will be very slow (wallclock) as each URL will
have to be fetched and encoded.
Configuration: via config file only
* import_image_timeout (seconds, default 3), initial connection timeout (not
overall file download)
* import_image_maxbytes (bytes, default 10MB): maximum image size to
download, checked before download (Content-Length) and validated
during (in case Content-Length is missing)
* import_image_regex (str), matches field content as "probably an
image", by default checks that the field value starts with
http|https and ends with an image-type extension (e.g. bmp, png, jpg)
Hard Limits:
* only works on fields actually called "icon", "image", "logo" or
"picture"
* the image can't be more than 42MP (checked after all data is
downloaded)
Hooks:
* _can_import_remote_urls (on res.users) checks whether the current
user is allowed to import via URLs
* _import_image_by_url (on base_import.import) performs the actual
download, could be overridden to store urls to import and
batch/queue the actual imports
