we need to see a feature to make the addons services renew dates auto sync with parent services .

this task can't be done with a custom plugin, it need a core
modification . in a lot of case the client renew the main service and
ignore the addons domain id the adons domain is ordered separately . and
others are claim about the prices , they need to pay just to the end of
term of the parent services .
