* strip rootfs prefix for run in docker
* Use `/` as default value of path.rootfs, and parse mounts from `/proc/1/mounts`.
* No need to mount `/proc` and `/sys` because we share host's PID
namespace, which allows processes within the container to see all of the
processes on the system.

* 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.

* 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)
instead of /sys/bus/cpu/devices/cpu[0-9]*.
The latter path also does not exist e.g. on RHEL 6.9's kernel.

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.

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: Support processor-less (memory-only) NUMA nodes
Processor-less (memory-only) NUMA nodes exist e.g. in systems that use
Intel Optane drives for RAM expansion using Intel Memory Drive
Technology (IMDT).
IMDT RAM expansion supports two modes:
* "Unify Remote Memory domains": present a processor-less (memory-only)
NUMA domain, which is the default
* "Expand local memory domains": to expand each processor’s memory domain
with a portion of the memory made available by Optane and IMDT
This commit fixes a crash in the first case (when "cpulist" is empty).
Here's an example of such a system:

* cpu: rename some variables (pkg => node)
* cpu: Use %v not %q in log.Debugf() format strings
* 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.
