Setting file mode at creation time avoids the time gap between open and chmod. See #21719

I don't feel the necessity of converting these errors to a CLIError. They should be propagated as it.
This also aligns with azure.cli.command_modules.vm._vm_utils.generate_ssh_keys_ed25519 (#30077):
azure-cli/src/azure-cli/azure/cli/command_modules/vm/_vm_utils.py

As IOError is no longer caught, this test is meaningless.

May I ask why we are using PrivateFormat.TraditionalOpenSSL instead of PrivateFormat.OpenSSH?

Good question!
PrivateFormat.TraditionalOpenSSL will generate a private key file like:
-----BEGIN RSA PRIVATE KEY-----
...
-----END RSA PRIVATE KEY-----
while PrivateFormat.OpenSSH will generate a private key file like
-----BEGIN OPENSSH PRIVATE KEY-----
...
-----END OPENSSH PRIVATE KEY-----
Using PrivateFormat.TraditionalOpenSSL makes sure there is no breaking change.

@yanzhudd Could you please help review it as well and do some simple tests? |

I used "az vm create" command to verify this command, and it did not generate any unexpected results.
