Would like to use subnet of hosts for collecting metrics from Prometheus exporter instead of list of IP's in hosts collection.

currently it supports

```auto
metricbeat.modules:
- module: prometheus
  period: 10s
  metricsets: ["collector"]
  hosts: ["172.0.0.7:9109"]
  metrics_path: /metrics

```

But would like to use something like below

```auto
metricbeat.modules:
# Metrics collected from a Prometheus endpoint
- module: prometheus
  period: 10s
  metricsets: ["collector"]
  hosts: ["172.0.0.0/16:9109"]
  metrics_path: /metrics

```
