[boost] [variant] Maintainer

Hi, I've been keeping an eye on Boost.Varinat for a few years. Since then multiple issues were closed; support for rvalues and variadic templates was added; other good things happened. Could I be promoted to an official maintainer of Variant? This will help me to react on issues faster (email notifications) which is essential. I'm also planning to add missing features from N4450 without affecting the current never-empty behaviour and without breaking existing code. -- Best regards, Antony Polukhin
