Bug Description

if the ofport of a port changes due to it being quickly unplugged/plugged (i.e. within a polling interval), the OVS agent will not update the ofport in its DVR cache of local port info so it will fail to be wired correctly.

    DVR: rebind port if ofport changes

    When binding is called in DVR, check to see if the port was
    previously wired under a different ofport. If it was, first
    unbind the old port and then bind the new one.

    Clear DVR MAC on last agent deletion from host

    Once all agents are deleted from a host, the DVR MAC generated
    for that host should be deleted as well to prevent a buildup of
    pointless flows generated in the OVS agent for hosts that don't
    exist.

    Add an option for WSGI pool size

    Neutron currently hardcodes the number of
    greenlets used to process requests in a process to 1000.
    As detailed in
    http://lists.openstack.org/pipermail/openstack-dev/2015-December/082717.html

    this can cause requests to wait within one process
    for available database connection while other processes
    remain available.

    By adding a wsgi_default_pool_size option functionally
    identical to that of Nova, we can lower the number of
    greenlets per process to be more in line with a typical
    max database connection pool size.

    DocImpact: a previously unused configuration value
               wsgi_default_pool_size is now used to a...
