As per prometheus/client_golang#543, pass the Registry for exporter
metrics when setting up the /metrics HTTP handler.
With this, the `promhttp_metric_handler_errors_total` metric will
increment on (possibly non-fatal) collection-time errors, such as
duplicate metrics from text files.

* 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.

The cpu frequency information is not always needed and/or available.
This change allows the cpu frequency metrics to be enabled/disabled
separately from the other cpu metrics, and also prevents a frequency
metric failure (such as a parse error) from failing the main cpu
collector.
Fixes#1241

* netclass_linux: remove varying labels from the 'up' metric
This moves the variable label values such as 'operstate' out of
the 'network_up' metric and into a separate metric called '_info'.
This allows the 'up' metric to remain continous over state changes.
Fixes#1236

* netstat: Add TCP In/Out Segs
In order to get a better idea of TCP packet loss, we need to know how
many `node_netstat_Tcp_OutSegs` there are so we can compare this to
`node_netstat_Tcp_RetransSegs`.

In https://github.com/prometheus/procfs/pull/100, the NFSTransportStats
struct was expanded by a field called protocol that specifies the NFS
protocol in use, either "tcp" or "udp". This commit adds the protocol as
a label to all NFS metrics exported via the mountstats collector.
