    Remove teardown.sh and update related docs

    The teardown.sh script attempts to provide a convenience, but is often
    left unmaintained. Because it is not maintained, it cannot fully tear
    down an environment. In addition, maintaining it has been made much
    harder since the introduction of independent role repositories - changes
    within those individual repositories would need to either be torn down
    in this script, or a tear down process in each role. Such a process
    would again face issues with maintenance.

    Also the teardown script has created bugs with installs started on a
    'dirty' environment. These behaviors have been hard to diagnose and fix,
    resulting in a lot of wasted time.

    Because of these issues, this patch removes the teardown script
    entirely, and alters the docs to recommend that AIOs are deployed to
    virtual machines for easier tear down and redeploy, as well as advising
    against any kind of production use.
