Description of problem:

The generateCatalogSource function does not generate an update strategy. This will be a problem when a targetTag is used for the catalog reference since there will be no way for the catalog to be automatically refreshed once oc mirror pushes a new catalog.

Below I've included an example CatalogSource purely for reference so you can see the update strategy portion of the YAML. For more information on this feature see Explanation of spec.updateStrategy and openshift docs for Catalog source. I'd recommend a hard coded default of {{30m0s}.

apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata: 
  name: my_example
  namespace: openshift-marketplace
spec: 
  displayName: example
  publisher: IBM
  image: icr.io/cpopen/ibm-cpd-platform-operator-catalog:v1.0
  sourceType: grpc
  updateStrategy:    # <-- this is not included
    registryPoll: 
      interval: 30m0s

Version-Release number of selected component (if applicable):

4.13

How reproducible:

always

Steps to Reproduce:

1. execute oc mirror and examine the catalog source that is generated

Actual results:

A catalog source that does not contain {{spec.updateStrategy}}

Expected results:

A catalog source that does contain {{spec.updateStrategy}}
