* Add a feature flag to enable the new manager
This PR creates a copy of the legacy manager and uses it by default.
It is a companion PR to #9349. With this PR, users can enable the new
discovery manager and provide us with any feedback / side effects that
the new behaviour might have.

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.

* PromQL: Fix start and end keywords masking label and metric names
This commit fixes an issue with the "at modifier" that introduced two
new keywords: `start` and `end`. In grouping options and in metric
names, these keywords took precedence over metric or label names, so
that those metrics and labels could no longer be referenced.

* 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.

prometheus_sd_discovered_targets is wrongly calculated when there are
multiple SD configurations in place. One discovery manager can have
multiple groups coming from multiple service discoveries.
When multiple service discovery configs are used, we do not compute the
metric correctly, and instead just set the metric to one of the service
discoveries.

This makes it clear that the dockerswarm package does more than docker
swarm, but does also docker.
I have picked moby as it is the upstream name: https://mobyproject.org/
There is no user-facing change, except in the case of a bad
configuration. Previously, a user who would have a bad docker sd config
would see an error like:
> field xx not found in type dockerswarm.plain
Now that error would be turned into:
> field xx not found in type moby.plain
While not perfect, it should at not be confusing between docker and
dockerswarm.

Label selector can be
"set-based"(https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#set-based-requirement)
but such a selector causes Prometheus start failure with the "unexpected
error: parsing YAML file ...: invalid selector: 'foo in (bar,baz)';
can't understand 'baz)'"-like error.
This is caused by the `fields.ParseSelector(string)` function that
simply splits an expression as a CSV-list, so a comma confuses such a
parsing method and lead to the error.
Use `labels.Parse(string)` to use a valid lexer to parse a selector
expression.
Closes#8284.

use ?wait=10m will give results as fast as usual when data is changing
but will perform far less requests when services do not change.
On large infrastructure, this will reduce quite a lot the number of
qps on Consul servers while having the same performance for freshness
of results.

Previously `max` results stopped reading from results in tests
prematurely, as it stopped when `max` number of items were received from
the channel instead of `max` number of unique target groups received.
This caused flaky tests where the same target group was received
multiple times, as Kubernetes informers may emit the same event multiple
times.
Before this patch, running this test repeatedly failed eventually. After
this patch I have run the test many thousand times without failure.

go test -run TestEndpointsDiscoveryNamespaces -count 1000 -test.v
