reserved_host_memory_mb should be set to 0 using ironic

[meizhifang]

In nova.conf,reserved_host_memory_mb default value is 512.But when using ironic,reserved_host_memory_mb must be set to 0.In class nova::compute::ironic,add code "'DEFAULT/reserved_host_memory_mb': value => '0';".

class nova::compute::ironic (
  $admin_user = 'admin',
  $admin_passwd = 'ironic',
  $admin_url = 'http://127.0.0.1:35357/v2.0',
  $admin_tenant_name = 'services',
  $api_endpoint = 'http://127.0.0.1:6385/v1',
) {

  nova_config {
    'ironic/admin_username': value => $admin_user;
    'ironic/admin_password': value => $admin_passwd;
    'ironic/admin_url': value => $admin_url;
    'ironic/admin_tenant_name': value => $admin_tenant_name;
    'ironic/api_endpoint': value => $api_endpoint;
    'DEFAULT/compute_driver': value => 'nova.virt.ironic.IronicDriver';
    'DEFAULT/reserved_host_memory_mb': value => '0';
  }
}

It should be a Puppet parameter which would be default to 512 (like nova upstream).
