Allow multiple TrustManagers

[Hakky54]

Hi @maxxedev I appreciate your PR and I can understand that in your usecase you might need to have a single trustmanagerfactory out of multiple trustmanagers, however I think there is a cleaner way to have this working instead of supporting multiple trustmanagers in a trustmanager factory. I created a specific trustmanager which can manage multiple trustmanagers properly. So I would suggest the following:

import nl.altindag.ssl.util.TrustManagerUtils;

import javax.net.ssl.TrustManagerFactory;
import javax.net.ssl.X509ExtendedTrustManager;
import javax.net.ssl.X509TrustManager;

public class App {

    public static void main(String[] args) {
        X509TrustManager trustManagerOne = null;    //TODO initialize your trustmanager here
        X509TrustManager trustManagerTwo = null;    //TODO initialize your trustmanager here
        X509TrustManager trustManagerThree = null;  //TODO initialize your trustmanager here

        X509ExtendedTrustManager trustManager = TrustManagerUtils.combine(trustManagerOne, trustManagerTwo, trustManagerThree);
        TrustManagerFactory trustManagerFactory = TrustManagerUtils.createTrustManagerFactory(trustManager);
    }

}

The combine method will use these two classes to properly use multiple trustmanagers, see here:

• CompositeX509ExtendedTrustManager
• CombinableX509TrustManager

Ok. Thanks!
