While installing an agent provider hosted cluster...

InfraEnv uses ignitionConfigOverride, however those overrides only apply to the discovery iso and do not persist to the Agent install.
 
Agent requires ignitionConfigOverrides (plural), the singular can be "saved" in the agent object w/out error but is immediately thrown out.

Agent should at least warn that ignitionConfigOverride is not valid, or perhaps even better accept both ignitionConfigOverride and ignitionConfigOverrides?

4.14    

Every time

    1. edit the agent object, add ignitionConfigOverride {}
    2. save the changes, no errors are raised
    3. check the agent object again, that param is gone since it was not accepted as valid, it only accepts the plural (ignitionConfigOverrides)     

    No change

    Override is applied
