Proposal: set cookie domain in pubcid / userid on main domain, not subdomain

[adxcgcom]

Type of issue

Feature request

Description

It is useful to have one pubCommonId for domain, not for each subsite.

As a possibile solution: in pbjs.setConfig publisher should set storage domain for cookie.

Steps to reproduce

In fresh browser open Prebid auction with pubCommonId / unifiedId module enabled.

After checking LOCAL set cookies in Chrome: Application->cookies we see that both modules set cookie domain to

subdomain.domain.com

it would be better to have this set at
domain.com (without subdomain), the same as other cookies.

Expected results

Set cookie domain to
domain.com

Actual results

Cookie domain is set to
subdomain.domain.com

The file modules/userId/index.js contains the setCookie call used by all the submodules, so the main domain could be passed as the domain argument for setCookie(key, value, expires, sameSite, domain, done). I'll create a PR for this fix
