Description of problem:

When there is an error generating the Ignition file by the AgentClusterInstall (on the infrastructure operator assisted installer), the GUI dont show the error.

In the Infrastructure->hosts you can see the hosts flipping from ready->preparing for install->ready. But you cannot see the error generated by the ACI:

"message": "Failed to prepare the installation due to an unexpected error: failed generating install config for cluster: [...] capability{\"NodeTuning\", \"ImageRegistry\", \"OperatorLifecycleManager\"}}: the Ingress capability is required\n: exit status 3. Please retry later",

Version-Release number of selected component (if applicable):

2.10

How reproducible:

In your Siteconfig, set the installConfigOverride wrongly. For example for 4.16 deployment:

installConfigOverrides: '{"capabilities": {"baselineCapabilitySet": "None", "additionalEnabledCapabilities": ["NodeTuning", "OperatorLifecycleManager"]}}' 

This will make Assisted Installer not able to generate the Ignition configuration showing the error on the ACI CR. But not shown on the ACM GUI.

Steps to Reproduce:

1. Generate a siteconfig with wrong capabilities
2. Wait the AssistedInstaller agent to do the work.
3. Infrastructure->hosts show hosts fliping from ready to preparing installation.

Actual results:

Expected results:
