Define a benchmark for hp tuning things

[petermattson]

Have a simple starter benchmark for comparing different hyperparameter optimization systems e.g. from Google, SigOpt, .... and open source efforts like https://github.com/kubeflow/katib

Supporting orgs: Cisco

Task 0: Enumerate some candidate opensource efforts and algorithms for hyperparameter tuning algorithms that we could consider (in addition to commercial software e.g. SigOpt, Google)

Task 1: Enumerate hyperparams for the workloads we might want to tune and their well known values from practice e.g. a subset of the reference workloads where hyperparam tuning has been used successfully.
