Fixes #11071
### Motivation
When the dataproxy module requests the
`/dataproxy/getIpList/inlong_agent_system` interface, an error occurs because
there is no record in the `inlong_group` table where the `inlong_group_id` is
equals to `inlong_agent_system`. This results in the manager console
continuously outputting exceptions
### Modifications
<!--Describe the modifications you've done.-->
- Changed getDataProxyNodes function in the
`org/apache/inlong/manager/service/cluster/InlongClusterServiceImpl.java` file
to throw an exception when there is no record in the `inlong_group` table where
the `inlong_group_id` is equals to `inlong_agent_system`
- Changed getIpList function in the
`org/apache/inlong/manager/web/controller/openapi/DataProxyController.java`
file to return fail response when an exception occurs in the
`getDataProxyNodes` function.
