Change initialization of JinjavaInterpreter to instantiation

[Roobun]

Now it's possible to override instantiate method
It'll be helpful if you use extended interpreter

I believe you will also have to look at https://github.com/HubSpot/jinjava/blob/master/src/main/java/com/hubspot/jinjava/Jinjava.java which also creates interpreters.

Maybe we can use a factory pattern for the JinjavaInterpreter and set the factory on the JinjavaConfig. So there would be some interface InterpreterFactory with a default JinjavaInterpreterFactory that is set as a field on JinjavaConfig. Everywhere we create a new interpreter would instead use config.getInterpreterFactory().newInstance(...). You could then create your own factory to serve your own interpreters and set that value in the config.

Sure. Please take a look at new changes I added.
