[Documentation] Improve documentation for overriding attributes from vmm_exec_kvm.conf

[paczerny]

Description There is an option to override the default configuration from vmm_exec_kvm.conf. User (admin?) can override the values in Cluster, Host and VM template. The latest has top priority. We have a list of configuration attributes in vmm_exec_kvm.conf But it's not clear which attributes can be overridden. Not all attributes can be defined in Cluster, Host and VM

Expected behavior Make a list or check box to define in which object the user can override the configuration attributes.
