[security-announce] Advance discontinuation announcement for openSUSE Leap 42.2

Hi folks, In around 2 months, at the end of January 2018, the SUSE support of openSUSE Leap 42.2 will end. This heads-up gives you time to migrate to openSUSE Leap 42.3, which continues to be supported until begin of 2019 at least. Please check https://en.opensuse.org/Lifetime for openSUSE lifetime information. Ciao, Marcus
