Add `rake gitlab:terraform_states:migrate` (to object storage)
Customers with deployments with files stored locally may wish to migrate the files to object storage. Maybe they are transitioning to Kubernetes.
But it looks like we don't have a task for:
- Terraform States
- Also, the upcoming Terraform::State::Version should be included in the same task
Add rake task to migrate to object storage, e.g.
rake gitlab:terraform_states:migrate=> !50740 (merged)
Add rake task to migrate to local storage, e.g.
rake gitlab:terraform_states:migrate_to_local(this could be a follow up, but it is not for nothing: we know the lack of rollback tasks has been a problem in the past) => #350187
Add docs for customers, maybe like https://docs.gitlab.com/ee/administration/raketasks/uploads/migrate.html, or search the docs for the other rake tasks
