    NSX-v3 update endpoint state only on timeout

    This patch removes the NSX v3 client cluster logic that
    forces a revalidate of all endpoints when endpoint
    selection only finds DOWN endpoints. The revalidate
    call can cause cascading backpressure under certain
    circumstances.

    Now DOWN endpoints are only returned to UP as part
    of the endpoint keepalive ping that is controlled via
    conn_idle_timeout config property. Thus, the default
    conn_idle_timeout is also decreased to 10s ensuring
    endpoint revalidation occurs (by default) on a fequent
    basis.
