*: add maintenance warnings

As of v1.0.0, fleet development and maintenance is no longer sponsored
by CoreOS. Add warnings to this effect.

-# How to Contribute
-
-CoreOS projects are [Apache 2.0 licensed](LICENSE) and accept contributions via
-GitHub pull requests.  This document outlines some of the conventions on
-development workflow, commit message formatting, contact points and other
-resources to make it easier to get your contribution accepted.
-
-# Certificate of Origin
-
-By contributing to this project you agree to the Developer Certificate of
-Origin (DCO). This document was created by the Linux Kernel community and is a
-simple statement that you, as a contributor, have the legal right to make the
-contribution. See the [DCO](DCO) file for details.
-
-# Email and Chat
-
-The project currently uses the general CoreOS email list and IRC channel:
-- Email: [coreos-dev](https://groups.google.com/forum/#!forum/coreos-dev)
-- IRC: #[coreos](irc://irc.freenode.org:6667/#coreos) IRC channel on freenode.org
-
-Please avoid emailing maintainers found in the MAINTAINERS file directly. They
-are very busy and read the mailing lists.
-
-## Getting Started
-
-- Fork the repository on GitHub
-- Read the [README](README.md) for build and test instructions
-- Play with the project, submit bugs, submit patches!
-
-## Contribution Flow
-
-This is a rough outline of what a contributor's workflow looks like:
-
-- Create a topic branch from where you want to base your work (usually master).
-- Make commits of logical units.
-- Make sure your commit messages are in the proper format (see below).
-- Push your changes to a topic branch in your fork of the repository.
-- Make sure the tests pass, and add any new tests as appropriate.
-- Submit a pull request to the original repository.
-
-Thanks for your contributions!
-
-### Coding Style
-
-CoreOS projects written in Go follow a set of style guidelines that we've documented 
-[here](https://github.com/coreos/docs/tree/master/golang). Please follow them when 
-working on your contributions.
-
-### Format of the Commit Message
-
-We follow a rough convention for commit messages that is designed to answer two
-questions: what changed and why. The subject line should feature the what and
-the body of the commit should describe the why.
-
-```
-scripts: add the test-cluster command
-
-this uses tmux to setup a test cluster that you can easily kill and
-start for debugging.
-
-Fixes #38
-```
-
-The format can be described more formally as follows:
-
-```
-<subsystem>: <what changed>
-<BLANK LINE>
-<why this change was made>
-<BLANK LINE>
-<footer>
-```
-
-The first line is the subject and should be no longer than 70 characters, the
-second line is always blank, and other lines should be wrapped at 80 characters.
-This allows the message to be easier to read on GitHub as well as in various
-git tools.
-
-## Adding Tests
-
-Ideally most functionalities should be covered by both unit tests and
-functional tests. This means, every time when you add a new functionality,
-you should also add unit tests, which is stored in *SRC_test.go*, as well as
-a [functional test](./functional/README.md), located under directory
-*./functional/*.
-
-Note that when adding a unit test under a new directory, you need to make sure
-that the new directory must be added to *TESTABLE* in [./test](./test). Without
-doing that, CI cannot run the new unit tests at all. Even build errors cannot
-be automatically detected.
