Chris Dent e1783b0087 Correctly limit provider summaries when nested
When making a GET /allocation_candidates request with the 'limit'
parameter, include all the providers in the same tree as the providers
mentioned in the allocation requests. That is, in a nested situation,
if we limit the allocation requests to 10, we would usually expect
considerably more than 10 providers in provider summaries, to include
any non-contributing providers in the same tree.

Accomplish this by filtering provider summaries on root_provider_uuid
instead of individual provider uuid.

A gabbi test is added which exercises this in a nested situation.

An existing test is updated to reflect the new filtering style. It
does not exercise the nested scenario.

A reno is added indicating the fix.

Limiting nested resource providers with the ``limit=N`` query parameter
when calling ``GET /allocation_candidates`` could result in incomplete
provider summaries. This is now fixed so that all resource providers that
are in the same trees as any provider mentioned in the limited allocation
requests are shown in the provider summaries collection. For more
information see `story/2005859`_.
