Wrong auctionDelay behavior in realTimeData module

[hierro1981]

Type of issue

auctionDelay in realTimeData behaviour isn't correct

Description

As per doc, auctionDelay should be an upper limit that RTD will wait for module with waitForIt at true for a response, but this is not the case.
Its managed as a fixed time the RTD will wait, also if the modules get the response before.

Steps to reproduce

set the following config for RTD:
realTimeData = { auctionDelay: 50000, dataProviders: [ { name: "ias", waitForIt: true, params: { pubId: "929966" } } ] }

set bidders timeout to 10000 and make a call.
Prebid will make IAS RTD module call, IAS give response after around 150ms, RTD module will wait for 50 seconds, after 10 seconds prebid will trigger timeout.

Expected results

RTD IAS module will make call, after having the response bidders start make request without waiting the 50sec auctionDelay.

Actual results

Platform details

Tested with Prebid v5.20.2 and v6.13.0

I believe this is a problem with the IAS rtd module, introduced in #7431 (@raguilar-ias can you verify?). callback is never called, so Prebid times out:

Prebid.js/modules/iasRtdProvider.js

Lines 140 to 150 in 887f703

	function getBidRequestData(reqBidsConfigObj, callback, config, userConsent) {
	const adUnits = reqBidsConfigObj.adUnits || getGlobal().adUnits;
	const { pubId } = config.params;
	const queryString = constructQueryString(pubId, adUnits);
	ajax(
	`${IAS_HOST}?${queryString}`,
	getApiCallback(),
	undefined,
	{ method: 'GET' }
	);
	}

I can confirm that we're looking into it on the IAS side.
