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.
