The option 'use_all_resource_revisions' is useful when using Gnocchi
with the patch introduced in [1]. That patch can cause queries to
return more than one entry per granularity (timespan), according to
the revisions a resource has. This can be problematic when using the
'mutate' option of Cloudkitty. Therefore, this option
('use_all_resource_revisions') allows operators to discard all
datapoints returned from Gnocchi, but the last one in the granularity
that is queried by CloudKitty. The default behavior is maintained,
which means, CloudKitty always uses all the data points returned.
However, when the 'mutate' option is not used, we need to sum all the
quantities and use this value with the latest version of the attributes
received. Otherwise, we will miss the complete accounting for the time
frame where the revision happened.
