This implements a CloudStack Prometheus exporter as a plugin, that serves
metrics on a HTTP port.
New global settings:
1. prometheus.exporter.enable - (default: false), Enable the prometheus
exporter plugin, management server restart needed.
2. prometheus.exporter.port - (default: 9595), The prometheus exporter
server port.
3. prometheus.exporter.allowed.ips - (default: 127.0.0.1), List of comma
separated prometheus server ips (with no spaces) that should be allowed to
access the URLs.
The following list of metrics are provided per pop (zone) with the exporter:
• Per host:
o CPU cores: used, total
o CPU usage: used, total (in MHz)
o Memory usage: used, total (in MiBs)
o Total VMs running on the host
• CPU cores: allocated (per zone)
• CPU usage: allocated (per zone, in MHz)
• Memory usage: allocated (per zone, in MiBs)
• Hosts: online, offline, total
• VMs: in all states -- starting, running, stopping, stopped, destroyed,
expunging, migrating, error, unknown
• Volumes: ready, destroyed, total
• Primary Storage Pool: (Disk size) used, allocated, unallocated, total (in GiBs)
• Secondary Storage Pool: (Disk size) used, allocated, unallocated, total (in GiBs)
• Private IPs: allocated, total
• Public IPs: allocated, total
• Shared Network IPs: allocated, total
• VLANs: allocated, total
Additional metrics for the environment:
• Summed domain (level=1) limit for CPU cores
• Summed domain (level=1) limit for memory/ram

I would love to see this method split. It doesn't fit in my mind. Guess it doesn't differ for the functionality.

I kept this method to follow the hierarical metrics output at host level in a zone; splitting may make redundant loops.

a lot of doublures in fields i.e. zoneName and zoneUuid or even zoneFilter. maybe a different hierarchy is an idea.

What approach should we take?
