* Use rsa-sha2-256 as the default SSH CA hash algo
As mentioned in the OpenSSH 8.2 release notes, OpenSSH will no longer be
accepting ssh-rsa signatures by default as these use the insecure SHA-1
algorithm.
For roles in which an explicit signature type wasn't specified, we
should change the default from SHA-1 to SHA-256 for security and
compatibility with modern OpenSSH releases.
