The aim of this "feature toggle" is to enable the unit price display for each product/variants.
By default activate on both development and staging environment.
This enables toggling features as best fits us in each case. With this
new approach we can then toggle :customer_balance to an entire instance,
which is what we want in France.
This enables the use of the new customer balance implementation to
whatever users we specify in the BETA_TESTERS env var through
ofn-install.
This var is meant to contain the user emails that will log in such as
personal accounts (I have an account with admin access to my hub) or
superadmin accounts used by the core team. This way can gather early
feedback ourselves while not releasing the new logic to users.
