Feature/jenkins plugins fact develop vrt

[zipkid]

Pull Request (PR) description

This PR changes the jenkins_plugins fact from a simple string value to a structured fact to avoid the error about a fact value being too long.

This Pull Request (PR) fixes the following issues

Fixes #1048

Maybe this gives too much information as the Hash contains much more than the name and version number that was in the 'old' fact.

It could easily be reduced to only some keys.
