RepartitionExec is missing BaselineMetrics #18218
Description
Is your feature request related to a problem or challenge?
BaselineMetrics is a set of common metrics for almost all operators, now RepartitionExec is not tracking it.
The BaselineMetrics output_rows and elapsed_compute are not showed in RepartitionExec in the below datafusion-cli reproducer:
