Release Manager dashboard: Group release pressure by Severity buckets
To help with #1055 (closed), it will be helpful to know not just how many Pick into
merge requests there are for each minor version, but what their severities are.
We should update the metric to group the number of MRs by priority labels (~S1 ~S2 ~S3 ~S4) and present them as a stacked bar graph.
