##### SUMMARY
<!-- Explain the problem/feature briefly -->
I've noticed that prometheus exporter and cloudmonkey reports the different
values for memory usage and allocated. See the output for more clarifications:
As you can see in the `node01` output the
`cloudstack_host_memory_usage_mibs_total` is `512.00` mibs which is equals to
`536870912`/`1024`/`1024`=`512` in cmk output for `memoryallocated`. The same
is true for mhz in cpu.

##### STEPS TO REPRODUCE
<!--
For bugs, show exactly how to reproduce the problem, using a minimal
test-case. Use Screenshots if accurate.
For new features, show how the feature would be used.
-->
1. Enable the prometheus if it hasn't been already enabled using the
"prometheus.exporter.enable" global setting.
2. Restart the mgt server if you enabled the prometheus.
3. Compare `listhostsmetrics` api call output with the prometheus output
using the above commands.
<!-- You can also paste gist.github.com links for larger files -->
##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
~~~
prometheus output matches the cmk outputs
~~~
##### ACTUAL RESULTS
<!-- What actually happened? -->
<!-- Paste verbatim command output between quotes below -->
~~~
prometheus output DOESN'T match the cmk outputs
