 If a Diagnostic is in the root array of the JSON, then it is shared, so it may be
 referenced by multiple Histograms. Shared Diagnostics must contain a string
 field `guid` containing a UUID.
 
 If a Diagnostic is contained in a Histogram, then it must not have a `guid`
 field.
 
 The other fields of Diagnostic dictionaries depend on `type`.

 This tracks buildbot parameters when the Histogram was produced to allow users
 to compare or merge results across similar bots.

Ben, do we want to replace this with anything else in the docs?

Not in this CL. I'll add a section about reserved names. Thanks for reminding
me!

 ### GenericSet
 
 This allows metrics to store arbitrary untyped data in Histograms.
 
  * `values`: array of any JSON data.
 
 ### Scalar
 
 Metrics should not use Scalar diagnostics since they cannot be safely merged.
