Bump cryptography for CVE-2024-12797

What does this MR do and why?

• Bump cryptography 43.0.1 > 44.0.1
• Refactor self-signed cert creation from OpenSSL.crypto.X509 to pyca/cryptography's X.509 APIs.

Resolves:

• CVE-2024-12797

Notes:

• Major bump, required change log analysis. Breaking changes in change log should not affect Crafty.
• Self signed certificate creation refactor was required, pyOpenSSL requires bumping to support the cryptography version we are moving to, But as a side effect of that the APIs that we are using to generate self-signed certificates through pyOpenSSL are deprecated, pyOpenSSL advises using cryptography APIs instead, Removing our need to have pyOpenSSL as a requirement.

  OpenSSL.crypto.X509. These should have been deprecated at the same time X509Extension was. Users should use pyca/cryptography's X.509 APIs instead.

How to set up and validate locally

• Clone and switch to branch.
• Ensure pem files do not exist from previous test build.
• Launch Crafty.
• Once craft he is fully started deck certificates are present in config folder.
• Restart crafty and ensure crafty can boot with the certificates existing.
