Bug Description

If I create more than one VM at a time (with nova boot option --num-instances), sometimes the flooding flow for broadcast, multicast and unknown unicast are not added on certain l2 agents.

And conversely, when I delete more than one VM at a time, the flooding rule are not purge on certain l2 agents when it's necessary.

I made this test on the trunk version with OVS agent.

    [ML2] l2-pop MD handle multi create/delete ports

    If more than one port is added or removed simultaneously, port db entry
    have status BUILD or DOWN and pass to ACTIVE when agent have finish to
    configured it.
    l2-pop mechanism driver use events port pass to ACTIVE or DOWN to send
    fdb entries. In case of port is the first or the last network port on
    an agent, the flooding entry need to be add or removed.

    This patch fix the method to determine how many ports are active on a
    agent by adding filter on status port to be ACTIVE.
