Description of problem:
In the inventory card in the systems dashboards, the counter for the baremetal hosts remains a gray fading square
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Open the dashboards page and look at the last line in the inventory card
It says:  Bare Metal Hosts
It should say: 3 Bare Metal Hosts
No relevant errors seem to be found in the browser console. There are some websocket connection errors and some svg errors.
I can reproduce this error in my cluster. The bug is caused by the absence of the node maintenance CRD/operator. The inventory card waits for the maintenance data to arrive and it never does.
After installing HCO in the cluster, this works as expected.
This is a problem, we can't rely on the presence of that node maintenance operator. The BaremetalHost inventory item should treat the maintenance as optional. There is an 'optional': boolean on FirehoseResource which we could use. Optional resources should not be taken into account when isLoading InventoryItem prop is calculated in InventoryCard. IMHO we should filter optional resources when additionalResourcesLoaded is calculated here https://github.com/openshift/console/blob/master/frontend/public/components/dashboard/dashboards-page/overview-dashboard/inventory-card.tsx#L75
