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.

* 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.

* 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

a label to all NFS metrics exported via the mountstats collector.

* cpu: Add a 2nd label 'package' to metric node_cpu_core_throttles_total
This commit fixes the node_cpu_core_throttles_total metrics on
multi-socket systems as the core_ids are the same for each package.
I.e. we need to count them seperately.
Rename the node_package_throttles_total metric label `node` to `package`.
Reorganize the sys.ttar archive and use the same symlinks as the Linux
kernel. Also, the new fixtures now use a dual-socket dual-core cpu w/o
HT/SMT (node0: cpu0+1, node1: cpu2+3) as well as processor-less
(memory-only) NUMA node 'node2' (this is a very rare case).

* cpu: Use the direct /sys path to the cpu files.
Use the direct path /sys/devices/system/cpu/cpu[0-9]* (without symlinks)

Netstat is 40% of the metrics on my laptop, many of which
are highly detailed information about IP internals in the kernel.
~300 such metrics on every machine in your fleet is excessive,
so focus on key metrics by default, overridable by the user.

* Interrupts counter should have _total
Linux "guest" metrics for VMs are already accounted for in node_cpu
`user` and `nice` metrics. Separate these into their own metric to
avoid duplication of data.
* cpu: Metric 'package_throttles_total' is per package.
'package_throttles_total' is per package, not per cpu. This also reduces
the total number of cpu time series a lot (esp for multi core cpus).
* cpu: Better handling of a cpulist edge-case.
* cpu: Extract the package number from the directory name.
Do not rely on the range index.
* cpu: Add package_throttle_count for node0 cpu1
This file must be ignored by the cpu collector.
