r/collectd-prometheus: Allow scraping from outside

Browse Source 
The *collectd-prometheus* role now has a
`collectd_prometheus_allow_outsize` variable.  This variable controls
whether or not external hosts are allowed to scrape data from *collectd*.
When set to `false`, as is the default value, *collectd* will be
configured to listen on the loopback interface only, and the TCP port
will not be opened in the firewall.
