added: Websocket Module setCustomClientBuilder

[djorkaeffalexandre]

Summary

With NetworkModule.setCustomClientBuilder we can customize our OkHttpClient to all requests made by react-native, it's very useful when you do SSL Pinning or change some OkHttpClient configuration at all. I've added a similar function to websocket, it allow us do some configurations on Websocket OkHttpClient.

[Android] [Added] - Websocket Module setCustomClientBuilder

Test Plan

You can just set a custom CustomClientBuilder on MainActivity onCreate:

import okhttp3.OkHttpClient;
import java.util.concurrent.TimeUnit;
import com.facebook.react.modules.network.CustomClientBuilder;
import com.facebook.react.modules.websocket.WebsocketModule;

public class MainActivity extends ReactFragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        RNBootSplash.init(R.drawable.launch_screen, MainActivity.this);

        WebsocketModule.setCustomClientBuilder(new CustomClientBuilder() {
            @Override
            public void apply(OkHttpClient.Builder builder) {
              builder.connectTimeout(0, TimeUnit.MILLISECONDS);
            }
          });
    }

@shergin do you know if someone can take a look here?
This is an important change for us on https://github.com/RocketChat/Rocket.Chat.ReactNative, since we need to allow users to pin a SSL Client certificate before connect to a server and it should be pinned at all the network layer.
If we get this merged, we don't need to create a fork of React Native.
Is there any chance of merge this?
Thanks a lot.

Any chance to get this in next release?
This is also important for WSS-Endpoints that require Client Certificates.
