List insight groups

List groups for which you are collecting insights ### Expanding the insight groups collection response LaunchDarkly supports expanding the insight groups collection response to include additional fields. To expand the response, append the `expand` query parameter and include the following: * `scores` includes details on all of the scores used in the engineering insights metrics views for each group * `environment` includes details on each environment associated with each group * `metadata` includes counts of the number of insight groups with particular indicators, such as "excellent," "good," "fair," and so on. For example, use `?expand=scores` to include the `scores` field in the response. By default, this field is **not** included in the response.
