Why there is no signal passed to final handler?

[jougene]

Issue Type

It would be better if we have signal in funally handler

Expected behavior

• we have signal in finally callback with proper logging on the application side

Actual behavior

• no signal in finally callback

Steps to reproduce the problem

• code example

    gracefulShutdown(app.server, {
      onShutdown: async signal => {
        logger.info('Handle shutdown: Started', { signal })

        await actual.stop()

        logger.info('Handle shutdown: App shutdown done', { signal })
      },
      finally: async signal => {
        logger.info('Handle shutdown: Active handles', {
          handles: process._getActiveHandles().map(handle => handle.constructor.name)
        })

        logger.info('Handle shutdown: Completed', { signal })
      }
    })
