Import example dashboards instructions

[leoauri]

Hi, it is impractical importing each of the many example dashboards individually, and this is the workflow linked to by the README. Therefore I suggest some pointer to the file /etc/grafana/provisioning/dashboards/sample.yaml which gives an example of adding a folder of dashboards for automatic provisioning. Cheers, Leo
