How to split ImageSetConfiguration and upload images using the oc-mirror plugin

Issue

• Due to this KCS issue, I need to split ImageSetConfiguration and upload images gradually because my environment has a slow network
• To begin, I have executed oc-mirror by using the following ImageSetConfiguration to generate mirror_seq1_000000.tar and uploaded the first Operator(s):

apiVersion: mirror.openshift.io/v1alpha2
kind: ImageSetConfiguration
mirror:
  operators:
  - catalog: registry.redhat.io/redhat/redhat-operator-index:v4.16
    packages:
    - name: cluster-logging

• Then I have executed oc-mirror with --skip-pruning by using the following ImageSetConfiguration to generate mirror_seq2_000000.tar and uploaded the second Operator(s):

apiVersion: mirror.openshift.io/v1alpha2
kind: ImageSetConfiguration
mirror:
  operators:
  - catalog: registry.redhat.io/redhat/redhat-operator-index:v4.16
    packages:
    - name: loki-operator

• Now, I notice that only the second operator is listed in the OperatorHub on the web console. The custom catalog image does not include the bundle for the first operator.
