Currently web-config is not a valid yaml and is an incomplete reference.
Keep the reference in README.md and create a minimalist web-config.yml
that acts as an exemple.

TCP "OutRsts" is the number of TCP Resets sent by the node. This can be
useful for monitoring connection failures and flooding.

We must know the length of the various filesystem C strings before
turning them from a byte array into a Go string, otherwise our Go
strings could contain null bytes, corrupting the label values.

The checkmetrics target currently uses promtool v2.5.0 which doesn't
include many improvements done over the time. This change also
simplifies the promtool installation, avoiding a temporary directory by
extracting the file directly to the target destination.

* The netdev collector CLI argument `--collector.netdev.ignored-devices` was renamed to `--collector.netdev.device-blacklist` in order to conform with the systemd collector. #1279
* The label named `state` on `node_systemd_service_restart_total` metrics was changed to `name` to better describe the metric. #1393
* Refactoring of the mdadm collector changes several metrics
- `node_md_disks_active` is removed
- `node_md_disks` now has a `state` label for "fail", "spare", "active" disks.
- `node_md_is_active` is replaced by `node_md_state` with a state set of "active", "inactive", "recovering", "resync".

We're looking to reuse this in Cortex to client side encrypt our
connections and not having this exposed is making us copy this entire
function.
