+Similar to adding maintainers, new sub projects can be added to containerd

+[charter](https://www.cncf.io/about/charter/) and mission. After a project
+proposal has been announced on a public forum (GitHub issue or mailing list),
+the existing maintainers are  given five business days to discuss the new
+project, raise objections and cast their vote. Projects must be approved by at
+least 66% of the current maintainers by adding their vote.
