In templates/utils/_daemonset_overrides.tpl,
$context.Values.__daemonset_yaml is used cross the loop. It is not deep
copied in each round of loop. It means that the property set in the
previous round of loop will still exist in current loop. This is not
expected.
This patch is to make a deep copy in each round of loop.
