Implementation of (weighted) Cohen's kappa

[csudre]

Is your feature request related to a problem? Please describe. Need for the Cohen's kappa (and its weighted variant) as additional metric for whole image classification

Describe the solution you'd like See the scikit-learn implementation of the measure defined as $\dfrac{p_o - p_e}{1-p_e}$ where $p_o$ is the observed probability of agreement and $p_e$ is the expected probability of agreement if samples were randomly labelled

@csudre, Are you working upon the implementation of Cohen's kappa in Monai? If not, then I'd love to contribute :)
