This enables the collection of pressure stall information as exposed
by the `/proc/pressure` interface added in the 4.20 release of the
Linux kernel.

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`.

* mountstats: Use new NFS protocol field
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.
