Remove support for VLAN networks

[Andreas Scheuring]

As we cannot support VLAN networks in release one, the support should get removed again.

This only affects the mechanism driver. In addition the devstack integration should be updated to use a flat provider network instead.

For nova this just means adapting the devstack local.confs - nothing else.

    Remove VLAN support

    This patch removes the VLAN support from the DPM Neutron
    mechanism driver.

    DPM adapters do not support VLAN tagging. Therefore the VLAN tagging
    must be done from inside the operatin system via a VLAN device.
    For automated configuration the operating system must be aware of the
    VLAN ID to be used.

    1) Ideally this information is part of the config drive. Then
    cloud-init can do all the configuration automatically.

    2) Alternatively the vlan-id could be passed in via the
    boot-os-specific-parameters property of a partition. But then some
    code inside of the operating system is required to interpret this
    data and configure the VLAN device. It's questionable if cloud-init
    would be able to deal with that.

    Due to 2) and to the fact, that Ocata release is near, we agreed
    to remove the VLAN support again. If one tries to attache an instance
    to a VLAN network, it will result in an error message. This is a
    clear statement that this is not supported.

    The VLAN code should be added again during Pike. Ideally in
    combination with the config drive 1). In the worst case using
    approach 2).
