BUG/MINOR: prevents unnecessary reloads due to CRD defaults.name

Since the default section name is hardcoded as `haproxytech`, every
event processed by the controller will trigger a hard reload,
regardless of the `spec.name` value the user passes in the
Defaults CRD (even if blank), because the comparison check will
never pass (unless the user sets exactly `spec.name = haproxytech`).
