Implement Index.__array_ufunc__

[TomAugspurger]

It'd be similar to Series.__array_ufunc__, (extract array, apply ufunc, box in index with name) with the exception that

1. No alignment when operating between multiple indexes
2. We'd need to decide whether Index or Series defers when calling ufuncs on inputs of mixed index and series. Check what binops does.

@TomAugspurger Would this be appropriate for first-time contributors? If so, I would like to work on this.

I'd recommend starting elsewhere. There's plenty of pandas-specific things that need to be taken into account, and we'll likely want to consolidate Index.__array_ufunc__ and Series.__array_ufunc__ into a single function, which might be tricky.
