Opening to track task of moving new plugin management repo to Jenkins.
Covered by HOSTING-777
https://github.com/jenkinsci/plugin-installation-manager-tool has been created. The next steps are to update the artifact id, move the code, and delete the original repo.
The repository has now completely been moved to jenkinsci. The artifact id was updated to match the repository name. The original repository was deleted and I started my own fork from the repository: https://github.com/stopalopa/plugin-installation-manager-tool. A pull request was created for update permissions: https://github.com/jenkins-infra/repository-permissions-updater/pull/1171. Some error was thrown when trying to merge the PR: https://ci.jenkins.io/blue/organizations/jenkins/Infra%2Frepository-permissions-updater/detail/PR-1171/1/pipeline/
This has been completed. We will need to address releasing the library when it's finished and updating the Jenkins file checks since this is not a plugin.
