When running tests in parallel, 10 milliseconds may not be enough for
all discoverers to register, which will make test flaky.
This commit changes the waiting logic to wait for number of discoverers
to stop increasing during given time frame, which should be large enough
for single discoverer to register in test environment.
A following run passes with this commit:
go test -failfast -race -count 100 -v ./discovery/kubernetes/

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

The Kubernetes client records workqueue duration and latency metrics as
seconds so there's no need to convert the values from microseconds to
seconds anymore.
The cache metrics (prometheus_sd_kubernetes_cache_*) are removed because
they aren't used anymore by the client though still exposed by its API.
