Use deprecation tag in NVT details

[swaterkamp]

What:
Added new isDeprecated() method to NVT model and add a note to NVT details.

Why:
Some NVTs are marked as deprecated but that information was not visible in the GUI. Using a new method for this one specific tag seemed the most clear usage.

How:
Added automated test for method and visually check the notification in NVT details for deprecated and non-deprecated NVTs.

Checklist:

• Tests
• CHANGELOG Entry
• Labels for ports to other branches
