Pivotal TrackerとSlackを連携する

追記

• コメント頂いた通り、 Pivotal Tracker Notifications (Legacy) で連携できます。Thanks @making@github

説明

• Pivotal Trackerでの更新をSlackで受け取りたいがIntegrationが見つからない :(
• https://www.pivotaltracker.com/integrations/slack はあったけど、これはFrom:Slack => To:Pivotal Trackerというかんじ。
• とにかく連携する方法が見つからないので書いてみた
• Pivotal Tracker側では Activity Web Hook をAddする

- Slack側では `Incoming WebHooks` を設定する - あとはコードをインストール、設定すると、Pivotal Tracker側の更新がSlackに通知される :)
