Add auc_type to h2o.performance() to compute multiclass AUC

[exalate-issue-sync]

I was looking at mutliclass AUC… it seems like there’s no way to compute this on the client side, after a model is trained. The only way is to set a non-default option for {{auc_type}} in any algo. We can add the {{auc_type}} option to {{h2o.performance()}} to pass it through and compute this for a test set.
