scripts: refactor scripts/download_hash.sh (#10713)
The new version brings the following improvements: - remove having to resort to python python to limit tags (it it slower than the sh equivalent as python has a somewhat significant startup time). - Introduce a concept of min version so that it can only get Kubernetes version supported by Kubespray. - Fix an issue with kata changing their file scheme (the arch specifically) - Now download sha256/sha256sum files if provided rather than downloading the full file and computing the hash - A few minor style tweaks Signed-off-by: Arthur Outhenin-Chalandre <arthur@cri.epita.fr.fr>pull/10998/head
