Allow customizing the sandbox provided to FastBoot about ember-cli-fastboot-testing

@ryanto, sorry I missed responding to the comment. That looks like a good Idea. Thank you for looking into that. I have some time right now. If you have can more detail on the generation logic, I can work on a PR for that.

@ryanto As discussed the sandbox Globals will include basic properties in the global scope. The Basic usecase we have is to set noop for clearInterval and throw an error for setInterval in fastboot environment. Example

let sanboxGlobals = {
   clearInterval: function() {
      // noop
  }
} 

const fastboot = new FastBoot({
    distPath,
    sanboxGlobal
});

Basically a hook during the setup which can take Globals object and passed on to the fastboot constructor as sandboxGlobals property.

Thank you for looking into this task.

Ok great!

I think the idea here will be to have the generator create a config/fastboot-testing.js file that will look something like this...

module.exports = {
  resilient: false,
  sandboxGlobals: {}
};

Addon docs does something similar for its custom config, so I'm going to steal that code :D
