Cookies: max-age

[indolering]

Edge does not support max-age in cookies, despite this being the standard. and supported by all other browser. This significantly reduces boilerplate required to set a cookies age and is supported by all other major browsers. Microsoft doesn't seem to care and it would be nice to add some pressure.

Would a PR adding this feature be welcome?
