TASK DESCRIPTION
Currently Scribunto creates profiling data on page parses, that is included
in the html source code (see below for an excerpt). Working on the performance
of the Wikibase Lua components, it would be helpful if we collected (in
Graphite, so that we can create a nice Grafana dashboard) this data.
In more concrete terms, it would be nice to have a whitelist of functions to
track, for which we will track how much time is spent in them globally (and
maybe how often they're called). On top of that, we should collect the overall
runtime of all Lua code (so that we have a reference metric, to set the
per-function data in context). With that we could adequately measure the impact
of Scribunto related changes.
