Retrieve users_count_threshold from the customers_app
In https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/6995 we implemented a basic Instance Review functionality. The default threshold of minimal users when the Instance Review is available was set to 100. The idea is that we can change the value dynamically, even on a daily basis.
In customers_app we implemented the possibility to change that value (https://gitlab.com/gitlab-com/customers-gitlab-com/merge_requests/265). The value is available on the endpoint /instance_review_threshold
with {"threshold":100}
as a response. The idea is to put it in a cronjob and run daily (for start)
