Restrict the output for a grouped expression to the k time series with the largest value
for the specified summary statistic. Example of usage:
| Before | After |

In some cases it can be useful to see an aggregate summary of the other time series that were not
part of the top set. This can be accomplished using the :topk-others-$(aggr) operators.
