### Description

The three commands:

```
              airflow users export /opt/airflow/dags/users.json &&
              airflow variables export /opt/airflow/dags/variables.json &&
              airflow connections export /opt/airflow/dags/connections.json
```

give back:

```
7 users successfully exported to /opt/airflow/dags/users.json
36 variables successfully exported to /opt/airflow/dags/variables.json
Connections successfully exported to /opt/airflow/dags/connections.json.
```


### Use case/motivation

Standardise output of "airflow connections export" to those of "airflow variables export" and "airflow users export"
