Create a home for internal gitlab unleash flags
This is a followup from !28980
We are sure that ops.gitlab.net is the best home for these, but at the time I started working on this, that instance was going through some changes. When the dust settles there we will know how to proceed.
For context see comments here: !28980 (comment 319594081)
Giving a weight of 3, one for each of the environments to support: production, staging, dev. Each environment should have it's own project which will house the flags for that environment.
