> Request:
> {{/api/v1/clusters/tdk/configurations/service_config_versions?fields=group_id,user&minimal_response=true&from=0&page_size=10}}
>
> Response always contains 10 records or less (if there are less than 10
> service configs versions). Each record has only two fields ({{group_id}},
> {{user}}).
> Request execution time depends on overall count of service config versions in
> the DB.
> Example:
> || Items Total in the DB || Response Time ||
> |2 |~140 ms|
> |100 |900+ ms|
> |290 |3+ s|
> |750 |9+ s|
> |1000 |15+ s|
> |3000 |30+ s|
