Add automated telegraf-agent upgrade workflow (#1652)
* Add automated telegraf-agent upgrade workflow Adds a scheduled GitHub Actions workflow that checks PMC daily for new telegraf-agent packages and creates PRs to update kubernetes/linux/setup.sh. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add upstream release notes to auto-generated telegraf upgrade PRs - Add 'Fetch upstream release notes' step that fetches from influxdata/telegraf GitHub releases using gh api (authenticated, best-effort with fallback) - Enhanced PR body with collapsible release notes, full release link, and compare link between versions - Use --body-file and env vars to safely handle multiline release notes containing special characters - Use unique delimiter for GITHUB_OUTPUT multiline values to prevent collision Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * chore: Rename check-telegraf-upgrade.yml to telegraf-upgrade.yml Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * chore: Rename workflow and fix PR body formatting - Rename workflow to 'Telegraf Package Upgrade' - Add co-authored-by trailer to commit message - Fix heredoc indentation for clean PR body rendering Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
