Description of problem:

Power metrics with units Watts(W) must be reported with metric name "hardware.ipmi.power" and not "hardware.ipmi.current"

| defa8232-8928-4608-8187-e61e16bd357e | ceilometer-high | hardware.ipmi.current | W | 87760997-1692-5ade-9d30-b12507ce8a44 |
~~~

The output of the command used to capture current metrics also includes power metrics, the readings are sampled as a current metric
without considering the type of sensor.
