This implements a CloudStack Prometheus exporter as a plugin, that serves
metrics on a HTTP port.

1. prometheus.exporter.enable - (default: false), Enable the prometheus
exporter plugin, management server restart needed.
2. prometheus.exporter.port - (default: 9595), The prometheus exporter

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
