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.

the `slug` is only present in the public images.
To refer a user-generated image (`snapshot` or `custom`) we can use

Last change in 4efca5a introduced a problem where NewDiscovery would
just return a nil value, which is not handled well and didn't allow for
fixing configuration issues at runtime without a reload.

This also caches credentials that are obtained e.g. via IRSA on AWS EKS.
Previously, every refresh cycle would request the credentials again.

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.

Added optional configuration item role, defaults to 'container' (backwards-compatible).
Setting role to 'cn' will discover compute nodes instead.
Human-friendly compute node hostname discovery depends on cmon 1.7.0:

Adjust testcases to use discovery config per case as two different types are now supported.
Updated documentation:
* new role setting
* clarify what the name 'container' covers as triton uses different names in different locations
