metrics-sockstat.rb does not output hostname as first field

[noahbailey]

When using this metrics plugin for Grafana via InfluxDB, it does not get added to the correct measurement.

Expected behaviour: The first field should contain the hostname of the server it runs on.
Observed behaviour: The first field is 'network' which puts all the metrics under the same measurement in InfluxDB making it rather useless for visualizations in grafana.

What it looks like:
network.sockets.total_used 298 1558632775

What it should look like:
my-server-name-here.network.sockets.total_used 298 1558632775

Appreciate all the work you guys do, thanks so much!

This is due to this line

You can adjust it using the --scheme flag but I agree it should match the format used here
