/**
* Restore original images from Azure Blob Storage when regenerating thumbnails via WP-CLI.
*
* As the Azure Blob Storage plugin offloads all media to Azure, we need to bring that media back
* to the local filesystem when we're regenerating thumbnails.
*
* This function very carefully determines if we're using WP-CLI's `media regenerate` command and,
* if so, determine whether or not the source file should be downloaded.
*
* Whether or not the file will be removed again is dependent upon the plugin settings; if the
* plugin has been instructed to remove media after moving it to Azure, the file we just pulled
* down (as well as its freshly-regenerated thumbnails) will be removed from the web server.
*
* Please note that while this executes on a WordPress filter (specifically "get_attached_file"),
* the value passed through the filter will *not* be modified. If, in the future, an action is
* added to `wp media regenerate`, it's recommended that this be rewritten to use that action
* instead of being a filter with side effects (albeit under a very specific use-case).
*
* @link http://wp-cli.org/commands/media/regenerate/
*
* @global $argv
*
* @param string $file The full system filepath for the image file.
* @param int $attachment_id The ID of the attachment we're resizing.
* @return string The unaltered $file string.
