ember-es6-class/no-object-extend rule

Hey @hmajoros, thanks for the issue, and this is a good question.

There's no real reason - we could likely add it to the rest of the rules to ensure we're covering all our bases.

Thanks for the suggestion!

@scalvert is there a reason we should be using no-extend-object over the combo of the standard Ember ember/no-classic-classes and ember/no-mixins? Seems like the combination of the two cover the enforcement of ES6 Classes and removing .extend which is only used for mixins at this point.

The only possible corner case I can see is that engineers are using ES6 classes with .extend outside of mixins, but that seems irresponsible considering they should just be using ES6 class extension.
