resource provider links list shows 'traits' in all microversions and should not

[Chris Dent]

When listing single or multiple resource providers, the JSON response includes a list of 'links' with each provider. These link to 'inventories', 'aggregates', 'usages' and 'traits'. Since 'traits' only showed up in microversion 1.6 the link to them should only be presented if the microversion is 1.6 or above.

The change to fix this is in the '_serialize_links' method in nova.api.openstack.placement.handlers.resource_provider.

    [placement] adjust resource provider links by microversion

    The resource provider representation includes links to other related
    resources. Those links should vary depending on microversion as some
    of the related resources did not show up until a later microversion.

    This change makes it so 'aggregates' show up at microverison 1.1 and
    beyond and traits in microversion 1.6 and beyond. A new gabbit has
    been added, resource-provider-links which exercises this. Only the
    single resource provider representation is tested because the same
    code is used for single and collection representations.
