Many collectors depend on underlying features to be enabled. This causes
confusion about what "success" means. This changes the behavior of the
`node_scrape_collector_success` metric.
* When a collector is unable to find data don't return success.
* Catch the no data error and send to Debug log level to avoid log spam.
* Update collectors to support this new functionality.
* Fix copy-pasta mistake in infiband debug message.

* Closes issue #261 on node_exporter.
Delegated mdstat parsing to procfs project. mdadm_linux.go now only exports the metrics.
-> Added disk labels: "fail", "spare", "active" to indicate disk status
-> hanged metric node_md_disks_total ==> node_md_disks_required
-> Removed test cases for mdadm_linux.go, as the functionality they tested for has been moved to procfs project.

* Add support for "linear" personality.
* Always set number of active disks to 0 when a device is inactive.
* Add total disks calculation to unknown personalites.

Named return variables should only be used to describe the returned type
further, e.g. `err error` doesn't add any new information and is just
stutter.
We seem to have a small number of Linux servers here that have lines in
/proc/mdstat that cannot be parsed by the node exporter, due to them
containing attributes that are not matched by the regular expression
("super 1.2").
Extend the regular expression to skip this data, just like we do for all
of the other status lines.
