Add a X.509 certificate example (#998)

Adds an example in rust for generating X.509 certificates using threshold Ed25519 and threshold ECDSA with curve secp256k1.
The example canister generates a root CA certificate.
The example canister generates child certificates for user-provided certificate signing requests.
Closes CRP-2583.
