MueLu: self-reported time does not always match time reported by application for Hierarchy setup
Created by: jhux2

In some cases, I've observed that MueLu's self-reported time for Hierarchy setup is significantly less than the time reported by the Nalu application.
Both use Teuchos timers. Nalu puts a timer around the call to CreateTpetraPreconditioner, MueLu starts/stops its timer at the beginning/end of Hierarchy::Setup.
Here's an example of the discrepancy:
MueLu: Hierarchy: Setup (total) 213.4 (600) 219.5 (721.9) 229.1 (1000)
nalu MueLu preconditioner setup 247.7 (200) 248.1 (200) 252.4 (200)
