[FEATURE] When the egress service recording is completed, return the node that completed the task.

[ananix]

Is your feature request related to a problem? Please describe. I have three egress service nodes, namely node1, node2, and node3. When recording is required, it will be randomly assigned to one of the nodes, and the file will also be randomly stored on the local disk of one of the nodes. However, I do not know which node completed the recording task.

Describe the solution you'd like Can the IP information of the node executing this task be returned at the beginning and end of the task?

Describe alternatives you've considered Notify through the response of the livekit.RoomCompositeEgressRequest interface or hooks callback..
