1. Proposed title of this feature request
Support enabling/disabling individual OLM catalogsource

2. What is the nature and description of the request?
Currently, disabling all default catalgsources is supported however in some cases, customers are looking to be able to disable a specific catalogsource. The HostedCluster CR seems to have the API included but it doesn't work when using something like below.

spec:  
  configuration:  
    operatorhub:  
      disableAllDefaultSources: false  
      sources:  
        - name: community-operators  
          disabled: true

3. Why does the customer need this? (List the business requirements here)
It is required in order to disable unused catalogsource.

4. List any affected packages or components.
HostedCluster, OLM, CatalogSource
