Authorizer for AWS sigv4 and cassandra-cpp-sys (DataStax cpp driver)

It uses AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, AWS_DEFAULT_REGION, AWS_REGION for configuration.

Example usage with cassandra-rs (cassandra-cpp crate): ``` use tokio; use std::fs;

use cassandracpp::*; use cassandrasigv4::*;

[tokio::main]

async fn main() { let mut cluster = Cluster::default(); cluster.setcontactpoints("cassandra.eu-central-1.amazonaws.com").unwrap(); cluster.set_port(9142).unwrap();

// Add these lines to use SigV4 authentication
let auth = Authenticator::default();
auth.set_authenticator(cluster.0);

let cert = fs::read_to_string("./sf-class2-root.crt")
    .expect("Certificate is missing");

let mut ssl = Ssl::default();
ssl.add_trusted_cert(cert.as_str()).unwrap();
ssl.set_verify_flags(&[SslVerifyFlag::NONE]);
cluster.set_ssl(ssl);

let session = cluster.connect().await.unwrap();
let statement = session.statement("SELECT keyspace_name FROM system_schema.keyspaces");
let result = statement.execute().await.unwrap();
for row in result.iter() {
    let keyspace_name: String = row.get(0).unwrap();
    println!("Keyspace: {}", keyspace_name);
}

} ```
