* discovery: check for nil triton_sd_config
Note: this was discovered thanks to the added test.
The test is pretty low-level but also effective.

* promql: Removed global and add ability to have better interval for subqueries if not specified
## Changes
* Refactored tests for better hints testing
* Added various TODO in places to enhance.
* Moved DefaultEvalInterval global to opts with func(rangeMillis int64) int64 function instead
Motivation: At Thanos we would love to have better control over the subqueries step/interval.
This is important to choose proper resolution. I think having proper step also does not harm for
Prometheus and remote read users. Especially on stateless querier we do not know evaluation interval
and in fact putting global can be wrong to assume for Prometheus even.
I think ideally we could try to have at least 3 samples within the range, the same
way Prometheus UI and Grafana assumes.
Anyway this interfaces allows to decide on promQL user basis.
Open question: Is taking parent interval a smart move?
Motivation for removing global: I spent 1h fighting with:
=== RUN TestEvaluations
TestEvaluations: promql_test.go:31: unexpected error: error evaluating query "absent_over_time(rate(nonexistant[5m])[5m:])" (line 687): unexpected error: runtime error: integer divide by zero
--- FAIL: TestEvaluations (0.32s)
FAIL
At the end I found that this fails on most of the versions including this master if you run this test alone. If run together with many
other tests it passes. This is due to SetDefaultEvaluationInterval(1 * time.Minute)
in test that is ran before TestEvaluations. Thanks to globals (:
Let's fix it by dropping this global.

Note that all new lines in the CHANGELOG except the last will
disappear in the final release because they only deal with issues
introduced in 2.20.0-rc.0.
This commit also adds an explanation for the WAL compression becoming
default.
Furthermore, this commit reverts the upgrade to grpc 1.30.0. It was
just a routine upgrade, but because grpc 1.30.0 contains two very
Go-module unfriendly breaking changes that in combination wreak havoc
for anyone importing from the prometheus/prometheus repo while still
depending on 1.29.1, we decided to revert as Prometheus itself doesn't
need the upgrade right now.
