[RFC00102] Increase Visibility and Access to Power Draw Data

[mikkokotila]

Background

As energy efficiency is becoming an increasingly important topic, we want to increase the visibility and access to power draw during and after the experiment.

Guiding Principles

• We don't want to create anything new here
• We simply want to tie together two parts of the system that have already been built

How will it work

• At the end of each permutation, calculate power draw data using the PowerDrawCallback
• Add total_power_draw as a new column to the experiment table in the DistributeScan central datastore

Historically related Issues

• autonomio/jako#10
• autonomio/talos#415

[mikkokotila]

In #584 I've updated the PowerDrawCallback to work with the latest changes in Tensorflow and improved the docs slightly. So for now this is enough. As long as the callback is used in the input model in DistributedScan or Scan then the power draw data will be visible.

Closing here.
