Review Comment:
Usually, Allocated space is the sum of used and reserved capacity. I'm not
sure if getting "usedCapacity" and showing it as "Allocated" is the right way.
@soreana Regarding the differences you are mentioning in the issue, the
"memoryused" from the hostreponse is from the
[hoststats](https://github.com/apache/cloudstack/blob/6125886f3d0b64ff3d0a743d00bf414774e7e2e3/server/src/main/java/com/cloud/api/query/dao/HostJoinDaoImpl.java#L227)
which is collected by stats collector from host and
"cloudstack_host_memory_usage_mibs_total" from Prometheus is the value from
"op_host_capacity" table (cpuCapacity.getUsedCapacity()).
If we want to show the same metrics in both hostmetrics and Prometheus then
we need to get the usedcapacity from hoststats and report it as "USED" only.
