🚀 [Feature]: Allow to stop the timestamp updater

[leonklingele]

Feature Description

There should be a way to stop the timestamp updater again so we don't leak a goroutine.

When using Uber's goleak you have to manually ignore these after shutting down the fiber server:

package handlers_test

import (
    "testing"

    "go.uber.org/goleak"
)

func TestMain(m *testing.M) {
    goleak.VerifyTestMain(
        m,
        // TODO: Fix those leaks upstream
        goleak.IgnoreTopFunction("time.Sleep"), // https://github.com/valyala/fasthttp/blob/0be5a4150cb0e35605cffd09e922707355dbdec3/fs.go#L477-L480
        goleak.IgnoreTopFunction("github.com/gofiber/fiber/v2/internal/memory.(*Storage).gc"),
        goleak.IgnoreTopFunction("github.com/gofiber/fiber/v2/internal/storage/memory.(*Storage).gc"),
        goleak.IgnoreTopFunction("github.com/gofiber/fiber/v2/internal/storage/memory.New.StartTimeStampUpdater.func1.1"),
        goleak.IgnoreTopFunction("github.com/gofiber/fiber/v2/utils.StartTimeStampUpdater.func1.1"),
    )
}

this concept was copied from fasthttp and is supposed to bring performance what is the alternative without the loss of performance ?

Just provide another function which stops the timer once started. This func should be called by whoever has started the timer after e.g. the fiber server was stopped.

This isnt proposing to get rid of the timer, just adding the ability to shut it down manually.

Ok, sorry misunderstanding Then sure we could do it
