Jenkins & Azure Repos

To enable Jenkins to fetch from Azure Repos (see lab):
- Steps:
  - Create a personal access token in Azure DevOps with read access & add it in Jenkins
  - Install TFS plugin (yet to be renamed Azure DevOps!) to Jenkins to allow:
    - TFVC: Poll & read & label
    - Git: Push trigger, build information fetching
- For auto trigger from Azure Repos:
  - Create service hook in Azure repos to trigger Jenkins build (official docs)
- To nest a Jenkins Job with Azure Pipelines
  - Add a service connection to Jenkins.
  - You can use Jenkin tasks such as Queue Jenkins Job, Download artifacts ...
  - 💡 Recommended as you can have end-to-end traceability from work items to source code to build and release pipelines.
