ml2 plugin may let hyperv agents ports to build status

[Francois Eleouet]

ml2 implementation of l2-population changed port status management workflow: when get_device_details is called on the plugin, corresponding port status is changed to "build", and agents are expected to call update_device_up/down once port details have been processed.

OVS and LB agents have been changed to update port status, but not hyperv agent, as a consequence, port plugged on hyperv agents may stay to 'build' status. Two solutions can be investigated to fix this issue:

-update_port_status plugin method should be called when port status changes to 'build'. hyperv mechanism driver would be notified and could re-set port status to 'active'

-hyperv agent could be changed to call update_device_up/down once a port has been plugged (but in that case, unchanged would still face the issue)

    Fixes port status hanging to build status

    ML2 plugin changes the port status to "build" when get_device_details
    is called. For this reason, the port status must be updated once the
    port details are processed.
