Currently, if we want to enable Host-specific setting of any applied class parameter value, we have to check the Override box by going to that Puppet class and selecting that variable. This has to be done for each parameter of each class of each module, that you may want to provide custom value for.

It would be better if we had a Foreman setting called Allow_overriding_all_Puppet_class_parameters where all Puppet class parameters would automatically be avaiable for Host-level overriding when editing a Host.
