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

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:
c1a2aeca36
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

We can assume that not all target groups are nil in normal scernarios,
so we can create targets[poolKey] outside the loop.

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.
