Rename main development branch from "master" to "main"
Over the last few years the development community has pushed towards more inclusive language for the main development branch in git repositories. Many repositories have settled on deprecating "master" in favor of "main", including mesa and libdrm. Such a change is consistent with the freedesktop.org Code of Conduct [1] section on using "welcoming and inclusive language".
Shall we make a similar change for igt-gpu-tools?
Is this a change that I can help push forward, or do we expect it will require a lot of gitlab admin stuff?
