runtime/metrics: docs reference nonexistent names and removed features #44280
Description
The docs on Sample specify that the Name field must be set to a description returned by Descriptions. I believe this should refer to All instead, because there is no identifier named Descriptions in package metrics.

Lines 13 to 18 in 0cb3415
Additionally, the package-level documentation mentions that Description values describe "how difficult or disruptive it is to obtain," but this information appears to have been removed in 8f6a9ac to save for the future. The only information of the style the documentation describes is whether a metric is cumulative.
