Start adding state annotations for diagnostic screen

Browse Source 
Summary:
The plan is to add such state annotations around all core sonar tasks, so the diagnostic screen can show a useful up to date picture of what's going on.
This is the first batch of such annotaions, to act as a tracer while putting the rest of the diagnostics code in place.
