Getting started / Readme

[capnbb]

Dear Team,

Firstly, many thanks for the v0.10.0 release

The lustrefs_exporter.service file includes this line:

Documentation=https://github.com/whamcloud/lustrefs-exporter

Would it be OK to have a README ?

Something similar to https://github.com/GSI-HPC/prometheus-cluster-exporter/blob/main/README.md might work.

By the way, we have your exporter running on a Lustre 2.16 cluster (ZFS OST),
Using this dashboard https://grafana.com/grafana/dashboards/17529-lustre/

any thoughts and advice welcome.

best regards

Jake
