Environment: everywhere

Url: https://console.dev.redhat.com/openshift/details/s/30MnSXizh4Iiiu3fGsOnAX5egYY#addOns

Browser: Any

OS: Any

Reproduction steps: 

• Open any Rosa HCP cluster details page 
• open the network panel of the browser devtools
• verify we are trying to fetch addons even if HCP doesn't support them

Current Result:

All API calls to GET /api/clusters_mgmt/v1/clusters/{clusterId}/addon_inquiries fail with HTTP 400 for Rosa HCP clusters. React Query will also retry those calls because they are failing but they will always fail.

Expected Result:

We don't fetch addons for Rosa HCP clusters because we know in advance they will fail.

Also because the message we show in the addons panel for HCP ("Coming soon Add-ons will be available soon for hosted control plane clusters.") is hardcoded and it doesn't depend on any API call.
