Node Exporter reports wrong file system metrics

[Pierre Riteau]

Node Exporter reports the same values for all node_filesystem_* metrics of a host, even though multiple file systems are mounted.

See the Node Exporter documentation for a configuration that fixes this issue: https://github.com/prometheus/node_exporter#docker

    Configure node-exporter to report correct file system metrics

    Without this configuration, all mount points are reporting the same
    utilisation metrics [1]. With the rslave option, all root mounts from
    the host are visible in the container, so we can remove the bind mounts
    for /proc and /sys.
