Expandable folders for environments
We implemented pagination of environments, but we decided in the first iteration to skip folder expansion as described by @dimitrieh in this note: https://gitlab.com/gitlab-org/gitlab-ce/issues/25499#note_20843634.
It seems that we have all backend required for this to work (API for in-folder review apps), so we would need now to allow expanding of folders which is pure ~Frontend . @filipa is that correct?
