Create pluggable Basic & Comprehensive diagnostics query #160
Description
For a while, I've wanted a query that runs when a dump is first loaded to run a lightweight set of diagnostics for known issues and reports those as yellow or red warnings on the Overview pane. Relatedly, there are more comprehensive diagnostics that might be useful to run non-automatically. There are various built-in reports that are in this realm such as Leak Suspects, Top Consumers, etc., but none of these are pluggable with extension queries. It would be nice to create some sort of extensible mechanisms with a standard API and standardized output for both lightweight on-load checks and more heavyweight manual checks that fall outside the scope of pure leaks. Opening this issue as a placeholder for now and hope to get a prototype at some point for discussion.
