Description of problem:
When one Catalog Source failed to run, the user cannot use another Catalog Source. we define a Subscription to use that worked Catalog Source, but OLM still read the failure one. That's unreasonable. Because we specify the `source` in the subscription explicitly. Why must OLM read all catalog sources?

How reproducible:
always

Steps to Reproduce:
1. Disable the default Catalog Sources
mac:kubernetes jianzhang$ oc patch operatorhub cluster -p '{"spec": {"disableAllDefaultSources": true}}' --type=merge

2. Install a customize catalog source called "community-operators", it failed to run since ImagePullBackOff error.

mac:kubernetes jianzhang$ oc get pods -n openshift-marketplace
NAME                                    READY   STATUS             RESTARTS      AGE

3, Install another catalog source called "qe-app-registry".

mac:kubernetes jianzhang$ oc get catalogsource qe-app-registry -o yaml

    serviceNamespace: openshift-marketplace


4. Subscribe to the aws-efs-csi-driver-operator, which from qe-app-registry catalog source.
mac:kubernetes jianzhang$ oc get sub aws-efs-csi-driver-operator -n openshift-cluster-csi-drivers -o yaml
apiVersion: operators.coreos.com/v1alpha1

  conditions:

    message: all available catalogsources are healthy
    reason: AllCatalogSourcesHealthy
    status: "False"
    type: CatalogSourcesUnhealthy
  - message: 'error using catalog community-operators (in namespace openshift-marketplace):
      failed to list bundles: rpc error: code = Unavailable desc = connection error:

    reason: ErrorPreventedResolution
    status: "True"
    type: ResolutionFailed
  lastUpdated: "2022-01-29T12:08:16Z"

Actual results:
1, That's unreasonable. In this aws-efs-csi-driver-operator subscription, it specifies the `qe-app-registry` Catalog Source, but it still read that `community-operators` Catalog Source. That's lead the subscription failed to run.

  - message: 'error using catalog community-operators (in namespace openshift-marketplace):
      failed to list bundles: rpc error: code = Unavailable desc = connection error:
      desc = "transport: Error while dialing dial tcp 172.30.36.150:50051: connect:

    reason: ErrorPreventedResolution
    status: "True"
    type: ResolutionFailed
  lastUpdated: "2022-01-29T12:08:16Z"

2, The community-operators Catalog Source didn't work well, but the status in the subscription display was healthy. As follows,

  catalogHealth:
  - catalogSourceRef:
      apiVersion: operators.coreos.com/v1alpha1
      kind: CatalogSource
      name: community-operators
      namespace: openshift-marketplace
      resourceVersion: "236975"
      uid: 08795f7b-4a05-4459-8210-b51fe505b948
    healthy: true
    lastUpdated: "2022-01-29T12:08:16Z"

mac:kubernetes jianzhang$ oc get pods -n openshift-marketplace
NAME                                    READY   STATUS             RESTARTS      AGE
community-operators-6wj49               0/1     ImagePullBackOff   0             23h
community-operators-qtmbg               0/1     ImagePullBackOff   0             23h


Expected results:
1, OLM should read the specified `source` directly, not read all catalog sources. Or, even if one catalogs source failure, it should not restraint the user use others.

2, Should display the right Catalog Source status in the subscription.

I also test it in the latest nightly payload, the same issue.

git commit: 5863540f44addf07e564b2e7c833c8a5f85841e7

Workaround:
Remove the issued Catalog Source. The subscription will be run successfully.
