Grouped findings

About this feature

Should have for Kennisnet phase: Epic-3
Must have for subsequent phase

Detailed description

Findings and objects should also be presented as group (identical finding/object-types should be shown once (perhaps foldable) with an indicator behind it how often it has been found.

Feature benefit / User story

As an administrator I want to group Findings and Objects, both in the Finding List and reports so that vulnerabilities can be more efficiently analyzed and resolved.
Example: groep an outdated software component, including the corresponding vulnerabilities (instead of only the vulnerabilities

This is important because it improves the information provision, so that the reader is better served and easier action can be taken to release findings in coherence.

Would you want this on the findings page, or in reports?

Lets provide a view on the findings page where we group by FindingType, and then show all occurrences of each finding in an indented, or folded view.
