shortid dependency uses cluster mode and hence loopback cannot run in Passenger

まだ誰も着手していません。

## Suggestion
shortid package uses nodes cluster mode. Passenger deployment environment does not support/allow for Nodes cluster mode. This becomes a blocker even when the shortid package feature not being used.

## Use Cases
loopback API to be deployed in Passenger environment.

## Examples
App 5797 output: Trace: You required the Node Cluster module, which is incompatible with Passenger, a non-functional shim was returned and your app may still work. However, please remove the related code as soon as possible.

## Acceptance criteria

TBD - will be filled by the team.

まず、Passenger のスタックトレースに示されている shortid 依存関係と cluster-worker-id.js のパスを追跡します。アプリケーションの起動時に依存関係がどのように読み込まれるか、またリポジトリに識別子の生成またはデプロイ互換性を対象とするテストがあるかを確認します。完了の定義はチームが決めるものとします。Passenger は互換性のない Node の cluster モジュールを必要とせずに起動し、識別子の動作は維持される必要があります。
