Currently we comment the operation_name attribute in the metadata that
it is used as an action name. This only creates confusion especially if
we want to use something different as the operation_name (i.e.
operation_name or opertaion_type for neutron router results in
"action"). So in addition to the renaming of the metadata attribute
explicitly pass the metadata operation key as operation_name parameters
into the generator (when unset).
