Update to the latest version of golang.org/x/crypto/ssh to add support of latest algorithms. At the same time use ssh.InsecureAlgorithms to support both ancient Ubuntu 14.04-era systems and daily Gentoo systems equally. Signed-off-by: Zygmunt Krynicki <me@zygoon.pl>

Pull Request Overview
This PR updates the SSH client configuration to support a broader range of SSH algorithms by upgrading to the latest version of golang.org/x/crypto/ssh and implementing a fallback mechanism for older systems.
- Updates golang.org/x/crypto and related dependencies to their latest versions
- Introduces
allAlgorithms()function that combines secure and insecure SSH algorithms for compatibility - Modifies SSH client configurations in both
client.goandopenstack.goto use the extended algorithm sets
