Support boot with extended resource request

Browse Source 
This adds the final missing pieces to support creating servers with
ports having extended resource request. As the changes in the neutron
interface code is called from nova-compute service during the port
binding the compute service version is bumped. And a check is added to
the compute-api to reject such server create requests if there are old
computes in the cluster.

Note that some of the negative and SRIOV related interface attach
tests are also started to pass as they are not dependent on any of the
interface attach specific implementation. Still interface attach is
broken here as the failing of the positive tests show.

Since neutron 19.0.0 (Xena), neutron implements an extended resource request
format via the the ``port-resource-request-groups`` neutron API extension. As
of nova 24.0.0 (Xena), nova does not support the new extension. If the
extension is enabled in neutron, then nova will reject server create and move
of nova 24.0.0 (Xena), nova does not fully support the new extension. If the
extension is enabled in neutron, then nova will reject server move
operations, as well as interface attach operation. Admins should not enable
this API extension in neutron.
Please note that Nova only supports the server create operation if every
nova-compute service also upgraded to Xena version and the
``[upgrade_levels]/compute`` configuration does not prevent
the computes from using the latest RPC version.
See :nova-doc:`the admin guide <admin/port_with_resource_request.html>` for
administrative details.
