Description
This PR is preparation step for adding support for Microsoft Entra ID (formerly Azure AD) authentication support

It introduces support for streaming credentials provider allowing connection re-authentication when new credentials are available.
Posible use cases is token based authentication (e.g. expiring tokens) or credential rotation.

PR introduces :

1. StreamingCredentialsProvider extending existing CredentialsProvider with option for providing a stream of credentials
2. If enabled connection will subscribe for credential updates and perform re-authentication

An example of credential provider supporting streaming : MyStreamingRedisCredentialsProvider
A basic usage would look like;

        MyStreamingRedisCredentialsProvider credentialsProvider = new MyStreamingRedisCredentialsProvider();
        
        RedisURI uri = RedisURI.builder()
            .withHost("REDIS_HOST")
            .withPort("REDIS_PORT")
            // use credential provider supporting credential stream
            .withAuthentication(credentialsProvider).build();  

        RedisClient client = RedisClient.create(uri);
        client.setOptions(ClientOptions.builder()
                 //enable re-authentication on new credentials
                .reauthenticateBehavior(ClientOptions.ReauthenticateBehavior.ON_NEW_CREDENTIALS)  
                .build());

        connection = client.connect()  
        ....
