feat(core): configurable cookie attributes

[MarcinSulowski]

Description

This PR makes it possible to overwrite the default attributes and create new ones for the locale, country and currency cookies.

Related Issue

CORE-6

Motivation and Context

This supports the use case where you have to set cookies on a parent domain to support differing subdomains for different sections of the website (setting the domain attribute for cookies). Additionally, you can overwrite the existing attributes or set new ones, if need be.

How Has This Been Tested?

Tested locally with the commercetools integration.
