🚀 [Feature]: Shutdown() add optional timeout

[pjebs]

Feature Description

Currently when I call Shutdown(), it seems to wait a long time (many minutes).

It would be good for it to pass in an optional ctx or a max wait time. If it hasn't gracefully shutdown by the max wait time, it hard kills the server connections etc.

Additional Context (optional)

As different as Shutdown(), we can add ShutdownWithContext(ctx) that checks ctx before graceful shutdowning

You can access fasthttp.Server with https://github.com/gofiber/fiber/blob/master/app.go#L852. But it's also OK to me add Close() method to Fiber.
