storage/remote: compute highestTimestamp and dataIn at QueueManager level
Because of relabelling, an endpoint can only select a subset of series
that go through WriteStorage

Having a highestTimestamp at WriteStorage level yields wrong values
if the corresponding sample won't even make it to a remote queue.

Currently PrometheusRemoteWriteBehind is based on that, and would fire
if an endpoint is only interested in a subset of series that take time
to appear.

A "prometheus_remote_storage_queue_highest_timestamp_seconds" that only
takes into account samples in the queue is introduced, and used in
PrometheusRemoteWriteBehind and dashboards in documentation/prometheus-mixin

Same applies to samplesIn/dataIn, QueueManager should know more about
when to update those; when data is enqueued.

That makes dataDropped unnecessary, thus help simplify the logic
in QueueManager.calculateDesiredShards()

Prometheus Mixin

This is work in progress. We aim for it to become a good role model for alerts and dashboards eventually, but it is not quite there yet.

The Prometheus Mixin is a set of configurable, reusable, and extensible alerts and dashboards for Prometheus.

To use them, you need to have jsonnet (v0.13+) and jb installed. If you have a working Go development environment, it's easiest to run the following:

$ go install github.com/google/go-jsonnet/cmd/jsonnet@latest
$ go install github.com/google/go-jsonnet/cmd/jsonnetfmt@latest
$ go install github.com/jsonnet-bundler/jsonnet-bundler/cmd/jb@latest

Note: The make targets lint and fmt need the jsonnetfmt binary, which is available from v.0.16.0 in the Go implementation of jsonnet. If your jsonnet version is older than 0.16.0 you have to either upgrade or install the C++ version of jsonnetfmt if you want to use make lint or make fmt.

Next, install the dependencies by running the following command in this directory:

$ jb install

You can then build a prometheus_alerts.yaml with the alerts and a directory dashboards_out with the Grafana dashboard JSON files:

$ make prometheus_alerts.yaml
$ make dashboards_out
