##### SUMMARY
<!-- Explain the problem/feature briefly -->
The prometheus integration returns inconsistent capacity values when a host
is in "maintenance" and cloudstack-management service is restarted.
##### 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.
-->
<!-- Paste example playbooks or commands between quotes below -->
~~~
1. Set "maintenance" status for a host
2. In database, the capacity rows are deleted in the op_host_capacity table,
for the said host
3. Prometheus integration returns capacities with value=0
4. Restart cloudstack-management service while the host is still in
maintenance
5. In database, table op_host_capacity is populated, with capacity_state =
Disabled
6. Prometheus integration now returns capacity values from
used/total_capacity columns, ignoring the capacity_state
~~~

##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
~~~
Prometheus integration returns capacity values=0 when the capacity is
missing (eg. host is in maintenance) or when the capacity_state is set at
Disabled (eg. host in maintenance and service is restarted)
~~~
##### ACTUAL RESULTS
<!-- What actually happened? -->
<!-- Paste verbatim command output between quotes below -->
~~~
Prometheus integration returns capacity values all the time as long as the
used/total_capacity columns exist, ignoring when the capacity_state is Disabled.
