Description of problem:
templates_service.add(tmpl, broken: true)
This will create template and silently ignore the broken parameter - it should raise an exception on unknown params

Version-Release number of selected component (if applicable):
ovirt-engine-sdk-4.0.1

How reproducible:
always

Steps to Reproduce:
equire "ovirtsdk4"
connection = OvirtSDK4::Connection.new({
    :url => 'https://hostname/ovirt-engine/api',
    :username => 'admin@internal',
    :password => 'password',
    :insecure => true,
})
system_service = connection.system_service
vms_service = system_service.vms_service
templates_service = system_service.templates_service
cluster = system_service.clusters_service.list[0]
vm = vms_service.list[0]

tmpl = OvirtSDK4::Template.new({
    :name => "template",
    :vm => {
      :id => vm.id,
    },
    :cluster => {
      :id => cluster.id,
    },
  })

templates_service.add(tmpl, broken: true)

Actual results:
ignores the parameter

Expected results:
should raise an exception

Additional info:
in python sdk it raises an exception
