Repeated cross-validation

[a976188d3c]

Is it currently possible to do a repeated cross-validation on a sl3 task similar to what is described in https://github.com/tlverse/origami/issues/3 or in https://mlr.mlr-org.com/articles/tutorial/resample.html

How the confidence bound for a performance measure, e.g., AUC, can be calculated if we do a repeated cross-validation on a sl3 task?

@rachaelvp has started to implement something like this. More work is needed
