Use the hostname instead of IP in the readme

Prior to this commit, the documentation stil specified `127.0.0.1` in
the examples. In a previous commit, this was changed to the FQDN of the
master and this commit updates the readme to use an example FQDN.

 You can search for useful information by performing a `grep` in the following format, run from inside the directory containing the metrics.
 
 ```
 cd /opt/puppetlabs/puppet-metrics-collector
