Added mountinfo changes to node_exporter (#1417)

Use the extra information gleaned from the mountinfo file to add
a 'mountaddr' field for NFS metrics. This helps prevent prometheus from
ignoring mounts that come from the same URL, but are actually from
different IP addresses.

This commit also rebases to current master
