Autodetection - setup system for validating the experiment results

[jbonisteel]

This is about setting up a system that allows us to estimate how accurate our loni metric is and what it's key evaluation metrics are.

As part of this activity the following tasks are needed:

• Research what can be used as a ground truth
• Build a ground truth to compare the analysis against
• Implement the ground truth to analysis comparison system
• Run the comparison and evaluate the performance of the model

This work is highly iterative and feeds directly back into the improvement of the analysis and is a precursor to completing the PoC of the analysis. It is however also very instrumental to getting this into production so it will continue going forward (especially the last 2 points about running it and improving the comparison system)

Most of the work for a first iteration of this has been completed in ooni/data#84 & ooni/data#21. We can consider this done.
