Add ability to get run by Git Commit Hash

[aslotte]

Is your feature request related to a problem? Please describe.
When setting up e.g. model tests after training has completed, we need the ability to fetch the latest run id that has been run.
This will allow us to either download that specific model or other operations.

Describe the solution you'd like
We want the ability to fetch a run by the git commit hash which we can associate with the model.
