### problem
DoD: Prometheus metadata is missing for the Prometheus exporter (TYPE and
HELP)
Currently the Prometheus exporter dumps a list of unsorted Prometheus
metrics without TYPE and HELP metadata.
The TYPE is for Prometheus to know what kind of metric it is, is it a gauge
or counter.
The HELP is for describing what the metric is and what for information it
provides
Under each section of TYPE and HELP combination the corresponding metrics
should be placed. Currently it is not sorted.
I've created a PR to order the metrics alphabetically. After that the
metadata (TYPE and HELP) is added. Currently I've set them all to type gauge,
although maybe some could be a counter (only going up or reset to 0).
example what is puts out now:
```
# Cloudstack Prometheus Metrics
cloudstack_host_is_dedicated{zone="nl-alk",hostname="peon1",ip="10.6.4.11"} 0
cloudstack_host_cpu_usage_mhz_total{zone="nl-alk",hostname="peon1",ip="10.6.4.11",overprovisioningfactor="1.0",filter="allocated",tags=""}

0.00
cloudstack_host_cpu_usage_mhz_total{zone="nl-alk",hostname="peon1",ip="10.6.4.11",overprovisioningfactor="1.0",filter="total",tags=""}
144000.00

cloudstack_host_memory_usage_mibs_total{zone="nl-alk",hostname="peon1",ip="10.6.4.11",overprovisioningfactor="1.0",filter="used",dedicated="0",tags=""}
17748.51
cloudstack_host_memory_usage_mibs_total{zone="nl-alk",hostname="peon1",ip="10.6.4.11",overprovisioningfactor="1.0",filter="total",dedicated="0",tags=""}
514654.53
cloudstack_host_vms_total{zone="nl-alk",hostname="peon1",address="10.6.4.11"} 5
cloudstack_host_vms_cores_total{zone="nl-alk",hostname="peon1",ip="10.6.4.11",filter="used",dedicated="0",tags=""}
5
cloudstack_host_vms_cores_total{zone="nl-alk",hostname="peon1",ip="10.6.4.11",filter="total",dedicated="0",tags=""}
48
cloudstack_host_is_dedicated{zone="nl-alk",hostname="peon2",ip="10.6.4.12"} 0
```
Provided fix should do:
```
# Cloudstack Prometheus Metrics
# HELP cloudstack_domain_limit_cpu_cores_total Total CPU core limit across
all domains
# TYPE cloudstack_domain_limit_cpu_cores_total gauge
cloudstack_domain_limit_cpu_cores_total 0
# HELP cloudstack_domain_limit_memory_mibs_total Total memory limit in MiB
across all domains
# TYPE cloudstack_domain_limit_memory_mibs_total gauge
cloudstack_domain_limit_memory_mibs_total 0
# HELP cloudstack_domain_resource_count Resource usage count per domain
# TYPE cloudstack_domain_resource_count gauge
cloudstack_domain_resource_count{domain="/", type="memory"} 0
cloudstack_domain_resource_count{domain="/", type="cpu"} 0
cloudstack_domain_resource_count{domain="/", type="gpu"} 0
cloudstack_domain_resource_count{domain="/", type="primary_storage"} 0
```
