After upgrading keda to 2.13.0 there seems to be a memory leak
Looking at go_goroutines metric I see the number growing indefinitely. Confirmed at least above 30k.
Here is a graph for go_goroutines.

I have deployed keda in different cloud vendor. I only see this issue in GCP.
Might be related to pubsub scalers I used only in GCP clusters.

Expected Behavior

memory/goroutine count remains somewhat constant.
You can see very clearly on the graph above when the upgrade to v2.13.0 happens.

Actual Behavior

memory increases indefinitely
