Adapt to new CSP design

[timja]

see jenkinsci/csp-plugin#16

Testing done

Tested it works if no CSP violations, haven't managed to test with something with violations, artifactory plugin test won't run on my machine, artifactory just won't start.

Submitter checklist

• Make sure you are opening from a topic/feature/bugfix branch (right side) and not your main branch!
• Ensure that the pull request title represents the desired changelog entry
• Please describe what you did
• Link to relevant issues in GitHub or Jira
• Link to relevant pull requests, esp. upstream and downstream changes
• Ensure you have provided tests - that demonstrates feature works or fixes the issue

Looks like LogParserTest is taking care of this for you?

[daniel-beck]

Haven't looked at LogParser in detail what exactly is happening there, but there is a legitimate regression in the CSP plugin here: DBS via Resource Root URL is deliberately intended to not have CSP, but now does. WIP fix in jenkinsci/csp-plugin#19
