Support wss with self-signed certificate

[cedricshih]

I am currently working on extending this library to accept our self-signed certificate without replacing default socket factory. My current attempt is to add socket factory members in WebSocketOptions.java:

public class WebSocketOptions {
    ...
    private SocketFactory mSocketFactory;
    private SSLSocketFactory mSslSocketFactory;

And initialized with default factories in default constructor:

    public WebSocketOptions() {
        ...
        mSocketFactory = SocketFactory.getDefault();
        mSslSocketFactory = (SSLSocketFactory) SSLSocketFactory.getDefault();

Also copied in clone constructor:

    public WebSocketOptions(WebSocketOptions other) {
        ...
        mSocketFactory = other.mSocketFactory;
        mSslSocketFactory = other.mSslSocketFactory;

Then in WebSocketConnection.java, create socket with factories in WebSocketOptions:

    private class WebSocketConnector extends Thread {

        public void run() {
                ...
                if (mWsScheme.equals("wss")) {
                    mSocket = mOptions.getSslSocketFactory().createSocket();
                } else {
                    mSocket = mOptions.getSocketFactory().createSocket();
                }

Do you accept patches? Or please consider to support this feature in other way. Thanks for your great work!

we should support TLS client connection options - which as a subproblem includes accepting self-signed certificates.

it is not a websocket options thing though, and it might also very well differ in how it is done in Android vs Netty

fwiw, related: #374
