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.

Java timestamps are causing issues when unmarshalling with a 32 bit
prometheus. It appears that we do not use those fields, so let's remove
them.

This also fixes a bug in query_log_file, which now is relative to the config file like all other paths.

Note: this was discovered thanks to the added test.
The test is pretty low-level but also effective.

We were missing testing on the behaviour of the configuration
unmarshalling.
This PR adds a refresh command that can be used to test that we
use the correct refresh function.

Since we dependend on go1.14 now, we can use T.Cleanup
https://golang.org/pkg/testing/#T.Cleanup
This provides a nicer approach to shut down the test server.

* OpenStack SD: Add availability config option, to choose endpoint type
In some environments Prometheus must query OpenStack via an alternative
endpoint type (gophercloud calls this `availability`.
This commit implements this option.

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