Hyper-V agent does not add new VLAN ids to the external port's trunked list on Hyper-V 2008 R2

[Alessandro Pilotti]

This issue affects Hyper-V 2008 R2 and does not affect Hyper-V 2012 and above.

The Hyper-V agent is correctly setting the VLAN ID and access mode settings on the vmswitch ports associated with a VM, but not on the trunked list associated with an external port. This is a required configuration.

A workaround consists in setting the external port trunked list to contain all possible VLAN ids expected to be used in neutron's network configuration as provided by the following script:

    Fixes Hyper-V 2008 R2 agent VLAN Settings issue

    This issue affects Hyper-V 2008 R2 and does not affect
    Hyper-V 2012 and above.

    Hyper-V agent now also sets the vswitch external port's
    DesiredEndpointMode to TRUNKED and adds the vlan_id in
    the external port's TrunkedVLANList.

    Note: This commit is not a classic backport, it is not merged in
    the master branch, since the Hyper-V Neutron Agent was decomposed from the master branch.
