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.
Fixes#515

Vmstat has over 100 fields, most of which are highly
detailed debug information. Trim this down to only
essential fields by default, configurable by flag.

* Only report core throttles per core, not per cpu
* Add topology/core_id to the cpu sysfs fixtures
* Add new cpu fixtures to ttar file
* Merge core_id reading and thermal throttle accounting
* Declare core_id
* updates for zfsonlinux 0.7.5
* add constants for KSTAT_DATA_* types
* added e2e test for negative values represented by uint64 that can result from ZFS bugs
Enable NFS client metrics by default now that it nolonger prints errors
on scrape if there are no metrics to display.
Also fixup the nfsd README to match the nfs entry.
All tools in OpenBSD base system use swpginuse instead of swpgonly
for reporting swap usage (snmpd, swapctl, top, vmstat), so let
memory collector use that as well for consistency.
* Add overlay to defIgnoredFSTypes
To avoid statfs() errors if node_exporter is running as non privileged user.
* Updated defIngoredFSTypes values in sorted order
* Update vendor github.com/prometheus/procfs/...
* Refactor NFS collector
Use new procfs library to parse NFS client stats.
* Ignore nfs proc file not existing.
* Refactor with reflection to walk the structs.
The node exporter runs unprivileged, so it cannot statfs any filesystems
under this directory causing log spam. In addition there tends to be
high churn in the filesystems here (as it's basically application
monitoring) which can cause high cardinaltiy and in one case caused
Prometheus's index symbol table to get very large.
Accordingly this should be ignored to reduce log spam and avoid
performance issues. The filesystems themselves can in principle be
monitored via container oriented exporters, and the underlying
filesystems will still be monitored.
