    Add support for managing async processes

    Interacting with a long-running asynchronous process requires the
    use of non-blocking io. This change adds a helper class that can
    launch a long-running process and read stdout and stderr in a
    non-blocking fashion via eventlet.

    This functionality is intended to support monitoring ovsdb via
    a long-running and root-privileged invocation of ovsdb-client.

    The complexity of the system interaction in this patch suggested
    the addition of a functional test that validated actual behaviour.
    The test was added under the neutron/tests/functional path which
    is now included in the testr search path.

    Partial-Bug: #1177973
