async fn image_exists_in_host_storage(image: &str) -> Result<bool>Expand description
Check if an image exists in the default containers-storage (podman storage).
TODO: Using exit codes to check image existence is not ideal. We should use the podman HTTP API via bollard (https://lib.rs/crates/bollard) or similar to properly communicate with podman and get structured responses. This would also enable proper progress monitoring during pull operations.
