Support for upcoming Chrome cookie policy change

Before the Chrome browser upgrade, the flag SameSite by default cookies was disabled by default. That is, cookies defaulted to 'SameSite=None'.

After Chrome 80 browser upgrade, SameSite by default cookies is enabled by default. That is, cookies now default to 'SameSite = LAX'. This impacts how cookies are handled when a Web page is opened in an iframe. Cookies, unless explicitly relaxed, will not be forwarded as part of the request, whenever the Web page is opened in an iframe of another domain.

This affects Cornerstone Saba - Cornerstone Classroom integrated environments. After setting 'SameSite=LAX' in Google Chrome, certain Cornerstone Classroom Admin pages that use iframes in Cornerstone Saba would not display correctly.

To address this change, the default value of 'SameSite' attribute will be set to 'None' in all cookies added by Cornerstone Saba servers, thereby allowing cookies to be sent across different domains.

Note: This change does not require any user action.
