Rafael Weingärtner a37dda5013 Use correct metadata for metrics gathered from gnocchi
Gnocchi fixed its `aggregates` API with PR
https://github.com/gnocchixyz/gnocchi/pull/1059. Before that patch,
the `aggregates` API would only return the latest metadata for the
resource of the metric being handled. Therefore, for CloudKitty
processing and reprocessing, we would always have the possibility of
using the wrong attribute version to rate the computing resources.
With this patch we propose to always use the correct metadata for the
processing and reprocessing of CloudKitty. This means, we always use
the metadata for the timestamp that we are collecting at Gnocchi.

The patch was released under version 4.5.0 of Gnocchi.

CloudKitty will always use the correct metadata for the
processing and reprocessing jobs. This means, we always use
the metadata for the timestamp that we are collecting at
Gnocchi backend.This is achieved with the use of
``use_history=true`` in Gnocchi, which was released under
`version 4.5.0 <https://github.com/gnocchixyz/gnocchi/releases/tag/4.5.0>`__.
Before that release, the ``aggregates`` API would only return
the latest metadata for the resource of the metric being handled.
Therefore, for CloudKitty processing and reprocessing, we would
always have the possibility of using the wrong attribute version
to rate the computing resources.
