Add feature flag to Instance, Group, Project level clusters
We need to place all the code that implements Instance, Group, Project level clusters under a dedicated feature flag
feature_flag_name
to be able to deprecate them safely (without removing them from the code)
Notes
- Including the APIs managing these
- We have GraphQL API + git to manage the Agent, but we don't have integrations with Terraform
