Profiler: Consider making default pop-up box less verbose

[manopapad]

The default pop-up box might contain a bit too many details for a casual user. Certain information (e.g. instance names) could be hidden behind a "show more" dialog. Might be good to make the hiding behavior configurable.

This is also a mixed issue. We can hide fields in the frontend but we'll still need the backend to tell us which fields should be hidden.
