outpost_service_connection_monitor leaking threads and ssh sessions

**Describe the bug**
Whenever the task `Update cached state of service connection.` (`authentik.outposts.tasks.outpost_service_connection_monitor`) runs, it seems to both leak threads (one of my worker processes is currently at over 2.6k threads and, when any instance of this task is running, is taking nearly 600% cpu of mostly kernel time) and ssh sessions on the outposts.

State of the worker:
```
$ pgrep -f authentik-worker | xargs -I{} grep Threads /proc/{}/status
Threads: 2
Threads: 2638
Threads: 1
Threads: 1
```
State of one of two of my outpost servers:
```
$ systemctl list-units --state=active | grep -E "Session [0-9]+ of User authentik" | wc -l
1313
```

**To Reproduce**
Steps to reproduce the behavior:
Set up an outpost integration using a ssh:// URL. Wait for the outpost_service_connection_monitor task to run a couple times.

**Expected behavior**
The sessions and threads should end.

**Logs**

The worker showed this one anomaly (though there are only /health request logs for a few days before, while the leak has been happening this whole time):
