    Use an actual existing nova scheduler in README.md

    The Multi-Node Setup guide in README.md

        https://github.com/openstack-dev/devstack/tree/master#multi-node-setup

    guides users to use

        SCHEDULER=nova.scheduler.simple.SimpleScheduler

    where the SimpleScheduler doesn't actually exist in nova. Even
    though this is just an example, it is misleading enough for a
    beginner to put SimpleScheduler into local.conf. The resulting
    error message where n-sch fails to start

        ImportError: No module named simple

    Isn't intuitive enough and may takes the beginner long time to
    locate what's wrong.

    This patch replaces SimpleScheduler with a real existing
    FilterScheduler in nova.
