Reference Issue

Rebased, squashed and resubmitted from PR #7569 after reviews.

What does this implement/fix? Explain your changes.

This adds a sample_weight parameter to sklearn.metrics.cohen_kappa_score. The implementation simply forwards the argument to the underlying confusion_matrix call.

Any other comments?

It would be better to add a specific test in test_cohen_kappa() (here), but I don't know how to get reference kappa values for this test. Note that cohen_kappa_score is removed from METRICS_WITHOUT_SAMPLE_WEIGHT in, which should provide additional testing, although not specific to this metric.

Finally I couldn't manage to run the full test suite locally so I'm relying on travis-ci here.

test_sample_weight_invariance() seems sufficient to me
LGTM, I merge since #7569 had already a +1.

Thanks @vpoughon
