    ovsdb monitor: handle modified ports

    This patch ensures that the ovsdb monitor propagates the events
    received for modified ports.

    We'll use a new list for the modified ports, which the neutron ovs
    agent can handle.

    In particular, this will cover the situation in which the ofport
    changes. When using recent OVS Windows versions, VM ofports change
    to -1 (invalid) when the VMs are shut down, receiving a valid
    ofport when the VMs are powered back on (different than the initial
    one). With this patch applied, "modify" events will be propagated
    to the ovs agent, which will then update the OpenFlow rules.
    The old rules are cleaned up by "update_stale_ofport_rules"
    once the invalid ofport is detected.
