[QuingKhaos]

Description

All project attributes which are affected by a namespace or path change are re-computed if changed and dependent resources on those attributes will be updated in the same run.

Closes: #874

PR Checklist

• (not applicable) Resource attributes match 1:1 the names and structure of the API resource in the GitLab API documentation.
• (not applicable) Examples are updated with:

  • A *.sh file for the resource/s with an import example (if applicable)
• (not applicable) New resources have at minimum a basic test with three steps:
