Add support for `cancelAllRuns` of any/all workflows

[GeekSheikh]

A user can submit a request to cancel all runs for a jobId. This does not result in individual "cancel" events (actions) so in this case all open runs should get an imputed closure for the jobId to close the run timestamp.

Do runs in progress already get closed? Need to check the data again.
