[PATCH v2 4/9] SubmittingPatches: discourage new trailers

["Josh Soref via GitGitGadget" <gitgitgadget@gmail.com>]

From: Josh Soref <jsoref@gmail.com>

There seems to be consensus amongst the core Git community on a working
set of common trailers, and there are non-trivial costs to people
inventing new trailers (research to discover what they mean/how they
differ from existing trailers) such that inventing new ones is generally
unwarranted and not something to be recommended to new contributors.
