Tetsuro Nakamura a40f6b08fa Return all resources in provider_summaries
The response of ``GET /allocation_candidates`` API provides two fields
of ``allocation_requests`` and ``provider_summaries``. The callers,
like the filter scheduler in nova, would use information in
``provider_summaries`` in sorting or filtering providers to allocate
consumers. However, currently ``provider_summaries`` doesn't contain
resource classes that aren't requested.

With this patch, ``GET /allocation_candidates`` API returns all
resource classes with a new microversion.

From microversion 1.27, the ``provider_summaries`` field in the
response of the ``GET /allocation_candidates`` API includes all
the resource class inventories, while it had only requested
resource class inventories with older microversions.
Now callers can use this additional inventory information in
making further sorting or filtering decisions.
