Currently we're hardcoding `job="prometheus-k8s"` as selector. This
doesn't work if your prometheus is elsewhere. Fortunately we have
`prometheusSelector` in `$._config` which all the other alerts use.
Use that here too.

The examples were still depending on an ancient prometheus
version. Updating caused some dependency shenanigans, but this should
work for now.

* Check syntax of example configurations
Fix a mistake in the hetzner and vultr configs.
Also it's easier not to fight the build system, and this will lint
example code, so ignore a lint issue in custom-sd.

This commit adds an alert in the prometheus mixin which triggers when
Prometheus has failed scrapes that have exceeded the configured
sample_limit for that job.

* Run gofumpt on all files
Getting golangci-lint errors when building on my laptop, possibly because I have newer version of gofumpt then what it was formatted with.
Run gofumpt -w -extra on all files as it will be needed in the future anyway.
* Update golangci-lint to v1.44.2
v1.44.0 upgraded gofumpt so bumping version in CI will help keep formatting correct for everyone
* Address golangci-lint error
Getting 'error-strings: error strings should not be capitalized or end with punctuation or a newline' from revive here.
Drop new line.

This commit removes the dependency between Prometheus and influx.
Note: Go keeps adding the indirect dependencies in go.mod, I can't
remove them.

We have been Puppet user for 10 years and we are users of
https://github.com/camptocamp/prometheus-puppetdb-sd
However, that file_sd implementation contains business logic and
assumptions around e.g. the modules which you are using.
This pull request adds a simple PuppetDB service discovery, which will
enable more use cases than the upstream sd.

* optimize Linode SD by polling for event changes during refresh
Most accounts are fairly "static", in the sense that they're not cycling
through instances constantly. So rather than do a full refresh every
interval and potentially make several behind-the-scenes paginated API
calls, this will now poll the `/account/events/` endpoint every minute
with a list of events that we care about. If a matching event is found,
we then do a full refresh.

* Fix: Use json.Unmarshal() instead of json.Decoder
See https://ahmet.im/blog/golang-json-decoder-pitfalls/
json.Decoder is for JSON streams, not single JSON objects / bodies.

Add cleanup of the lockfile when the db is cleanly closed
The metric describes the status of the lockfile on startup
0: Already existed
1: Did not exist
-1: Disabled
Therefore, if the min value over time of this metric is 0, that means that executions have exited uncleanly
We can then use that metric to have a much lower threshold on the crashlooping alert:
If the metric exists and it has been zero, two restarts is enough to trigger the alarm
If it does not exist (old prom version for example), the current five restarts threshold remains
