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.

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.

Currently Prometheus requests show up with a UA of Go-http-client/1.1
which isn't super helpful. Though the X-Prometheus-Remote-* headers
exist they need to be explicitly configured when logging the request in
order to be able to deduce this is a request originating from
Prometheus. By setting the header we remove this ambiguity and make
default server logs just a bit more useful.
This also updates a few other places to consistently capitalize the 'P'
in the user agent, as well as ensure we set a UA to begin with.
