Add benchmarking and physics validation of outputs to pipeline

[benkrikler]

Imported from gitlab issue 4

Ideally using scikit-validate, the pipeline would benchmark it's performance, and also compare that no distributions have changed (unless this is expected). Since this is a nightly build and not a Merge Request, there'd need to be some consideration for how to report these results back, nightly email? Issue opened if things change in unexpected ways?

Issue opened if things change in unexpected ways?

That is doable. For LZ + scikit-validate we have the bot posting to an MR but the same can be done for an issue.
What you need to define, and that's WIP for skvalidate, is what warrants a big enough problem for a test to fail.
