"GeolocationDispatcherHostImpl" is not a very semantically contentful string in
the context of a metrics dashboard, nor is it super likely to remain unchanged
over the long term.  Is there perhaps a more conceptually clear name that you
could use for this metric?  Perhaps something like
"Geolocation.RendererRequest.ErrorCode"?

Done.
