Make DataFrame Consuming

[tustvold]

Is your feature request related to a problem or challenge? Please describe what you are trying to do.

Currently all of the various methods on DataFrame take &self, and a number of methods return Arc<DataFrame>.

This results in a non-trivial amount of unnecessary clones, in particular of LogicalPlan which is not especially cheap.

Describe the solution you'd like

I would like methods to return DataFrame instead of Arc<DataFrame> and for the member functions on DataFrame to capture self

Describe alternatives you've considered
