Admission Webhook not called when forcefully closing RTMP client

[bartvp1]

Describe the bug
The admission webhook for closing RTMP streams is not called when a it closes unexpectedly

To Reproduce
Steps to reproduce the behavior:

1. Set up OME with RTMP ingress & admission webhooks
2. Start a RTMP stream using Larix
3. Disable the internet connection on the broadcasting device

Expected behavior
The admission webhook should be called with the information of the cancelled RTMP stream

Server

• OS: Ubuntu
• OvenMediaEngine Version: 0.16.5

[getroot]

OME may not be aware that the RTMP session has been disconnected. If TCP keepalive is working, OME will notice the tcp connection termination after several tens of seconds. Admission webhooks aren't being called even though the log shows the stream has been deleted?

[bartvp1]

The logs don't show anything in regard to the disconnected RTMP client.

Any updates on this issue?

I need this feature because I need to keep track of active streams in a separate, realtime database.
I investigated whether syncing the redis server (origin map store) would fix this issue, but OME keeps sending SET and EXPIRE commands to the Redis server, despite not receiving any new frames. This results in streams still remaining while they are not.
