[kata-dev] Migration to Kata 2.0, and support timeline for 1.x

Hey kata folk -- With 2.0 out now, we are focusing continued development and improvements on the 2.0 code base. As a result, in a prior architecture committee meeting discussion, we made the decision on a 6 month window (from release of 1.12) before stopping regular support of the 1.x (1.11 and 1.12 currently) branches. Based on this, here's a first heads up! We plan to deprecate support for 1.x on May 12th 2021. Thanks! Eric
