KISS function to generate a self signed certificate

Given a set of domain names you want your certificate to be valid for, this function fills in the other generation parameters with reasonable defaults and generates a self signed certificate and key pair as output.

Example

use rcgen::{generate_simple_self_signed, CertifiedKey};
// Generate a certificate that's valid for "localhost" and "hello.world.example"
let subject_alt_names = vec!["hello.world.example".to_string(),
	"localhost".to_string()];

let CertifiedKey { cert, key_pair } = generate_simple_self_signed(subject_alt_names).unwrap();

// The certificate is now valid for localhost and the domain "hello.world.example"
println!("{}", cert.pem());
println!("{}", key_pair.serialize_pem());
