merge: Fix distributed strategy for TensorFlow experiment (#89)

This pull request fixes an issue where the distributed strategies for the 
TensorFlow experiments did not work correctly.

## Implementation Notes :hammer_and_pick:

* Limit growth rate for trace construction
* Derive device statistics directly from SimMachine 
* Always recompute power usage when a `SImBareMetalMachine` converges
* Add a test case for `MirroredStrategy`
