This is the release-4.19 clone to backport the interval change for refreshing the catalog cache data for catalog-operator from 5 minutes to 30 minutes. 

--------------

When trying to install an operator, the below is logged:

"Warning alert:CatalogSource health unknown This operator cannot be updated. The health of CatalogSource "redhat-operators" is unknown. It may have been disabled or removed from the cluster.CatalogSource CSView CatalogSource

1. The underlying error in logs is 

   msg="error encountered while listing bundles: rpc error: code = DeadlineExceeded desc = context deadline exceeded" catalog="{redhat-operators openshift-marketplace}

1. As discussed we could not reproduce this locally and have attempted multiple times to simulate the appropriate grpc connection and exact api call,  which succeeded for us.
2. Therefore the suspected cause is a network issue on the customer’s cluster,  and we require full cooperation from a qualified cluster/network professional on the customer end who is aware of their exact config, and a detailed network dump/analysis what actually happened at the point in time when OLM got this timeout.
3. We cannot proceed with investigation based on the current info we have.
