Rationale for this change

The body of RepartitionExec::execute is long and highly indented, and has a bunch of metrics related code that obscures how it works, in my opinion.

What changes are included in this PR?

As suggested by @tustvold in #521 (comment), attempt to make the code clearer and error conditions easier to reason about by:

Changes:

  1. Factor the body of the repartition into its own async function
  2. Grouped the metrics into a RepartitionMetrics struct for convenience
  3. Refactored repeated code into SQLMetric::add_elapsed and reduced duplication

I still think the metrics could still be made better, and I hope to work on that at a later date.

Are there any user-facing changes?

No
