Set container context with static method, so it is not required to pass context to Container.defaultContainer method

[Steven-Chan]

Reason:
context passed to defaultContainer is useless after the first time called and the container is initialized.

This can reduce code repetitiveness, and can be used without context, which is actually useless most time.

New API

Container

public static Container defaultContainer() { ... }
public static void configure(Context context, Configuration config) { ... }

Usage

Current

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();

        Configuration config = new Configuration.Builder()
                .endPoint("https://<your-app-name>.skygeario.com/")
                .apiKey("<your-api-key>")
                .build();

        Container.defaultContainer(this).configure(config);
    }
}

// somewhere else inside an Activity
Container.defaultContainer(this).callLambdaFunction(...);

Proposed

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();

        Configuration config = new Configuration.Builder()
                .endPoint("https://<your-app-name>.skygeario.com/")
                .apiKey("<your-api-key>")
                .build();

        Container.configure(this, config);
    }
}

// somewhere else inside an Activity
Container.defaultContainer().callLambdaFunction(...);

Considering compatibility,

// these are still valid
Container.defaultContainer(this);
Container.defaultContainer(this).configure(config);

// this will throw exception, if Container.configure not called before
Container.defaultContainer();

I think this is no longer valid after the new API grouping?

[Steven-Chan]

@rickmak This is still valid actually.
