RFR: 6626: The halt rule result should have a table of the VM operations [v2]

[Suchita Chaturvedi]

> Added top 5 vm operations (ordered by max time), including the thread that initiated them.
> Since the halt rule was pointing to VM operation rule in its description, hence i have added the table to vm opertion rule itself where it was more related to.
> 
> The rule looks something like this now.
