Update repository parameters to include extended release information, using features api to filter out items the user doesn't have a subscription. For example, a user could have rhel 8.8 but not 8.4 (eus vs e4s)

The API could add a new field that looks something like this, to make it easy for the UI to have a separate dropdown for minor release versions

 "distribution_minor_versions": [
      {"name": "el8.6", "label": "8.6", "major": "8"},
      {"name": "el8.8", "label": "8.8", "major": "8"},
      {"name": "el8.10", "label": "8.10", "major": "8"},
      {"name": "el9.0", "label": "9.0", "major": "9"},
      {"name": "el9.2", "label": "9.2", "major": "9"},
      {"name": "el9.4", "label": "9.4", "major": "9"}
    ],
