Rclone storage backend (#4402) * Add Rclone storage backend * Support templating the name of files stored via Rclone * Enable Rclone accounting * Remove redundant type conversion * Provide progress information for Rclone download/upload operations * Log error when Rclone can't instantiate filesystem * Remove filename templating functionality for Rclone storage To (maybe) be later reintroduced as a generic functionality for all storage backends. * Remove S3 specific check * Move Rclone config initialisation to init() method 2023-04-19 05:12:12 +08:00			`package rclone_backend`
