[dichotommy]

There are some new telemetry metrics as part of the changes to the tasks API:

| `per_task_uid`          | `true` if an uid is used to fetch a particular task resource, otherwise `false` | true |
| `filtered_by_index_uid` | `true` if `GET /tasks` endpoint is filered by `indexUid`, otherwise `false` | false |
| `filtered_by_type`      | `true` if `GET /tasks` endpoint is filered by `type`, otherwise `false` | false |
| `filtered_by_status`    | `true` if `GET /tasks` endpoint is filered by `status`, otherwise `false` | false |
