Currently, when the prometheus datasource query ceilometer_cpu metric
for instance cpu usage, it aggregates by instance and filter by the
label containing the instance uuid. While this works fine in real
scenarios, where a single metric is provided in a single instance, in
some cases as the CI jobs where metrics are directly injected, leads to
incorrect metric calculation.
We applied a similar fix for the host metrics in [1] but we did not
implement it for instance cpu.
I am also converting the query formatting to the dict format to improve
understability.
