fix: activity id to chain id quote injector and lambda handler event

[jsy1218]

During container injector, we instantiate a new global logger with injector-sor, without request id, or any identifier that can identifier which request it's part of:

    const log: Logger = bunyan.createLogger({
      name: this.injectorName,
      serializers: bunyan.stdSerializers,
      level: bunyan.INFO,
    })
    setGlobalLogger(log)

The reason for this is because, buildContainerInjected() is called as part of QuoteHandlerInjector('quoteInjector').build(), but we only start to get the request id from the lambda event within new QuoteHandler('quote', quoteInjectorPromise)
, within injector:

  public async getRequestInjected(
    containerInjected: ContainerInjected,
    _requestBody: void,
    requestQueryParams: QuoteQueryParams,
    _event: APIGatewayProxyEvent,
    context: Context,
    log: Logger,
    metricsLogger: MetricsLogger
  ): Promise<RequestInjected<IRouter<AlphaRouterConfig | LegacyRoutingConfig>>> {
    const requestId = context.awsRequestId
  ...

log = log.child({
      serializers: bunyan.stdSerializers,
      level: logLevel,
      requestId,
      quoteId,
      tokenInAddress,
      chainId: tokenInChainId,
      tokenOutAddress,
      amount,
      type,
      algorithm,
      gasToken,
    })
    setGlobalLogger(log)
}

So this means we need to manually generate a new random identifier within injector-sor activityId, and pass into injector, so that we have the way to identify which request is this container injection from. In addition, because not every request needs the container injection, the activity id has to be optional. I verified in my local and can now see activityId popping up and tieing up the loggings within the same request:

I also tested non-cold start scenario, and can see there's no activity id, only request id:
