Allow escaping a dollar sign when expanding external labels (#10129)
* Allow escaping a dollar sign when expanding external labels

There is currently no mechanism to natively escape a dollar sign
in the os.Expand function. As a workaround, this commit modifies
the external label expansion logic to treat a double dollar ($$)
as a mechanism for escaping the dollar character.

beorn7 b39f2739e5 PromQL: Always enable negative offset and @ modifier
This follows the line of argument that the invariant of not looking
ahead of the query time was merely emerging behavior and not a
documented stable feature. Any query that looks ahead of the query
time was simply invalid before the introduction of the negative offset
and the @ modifier.

beorn7 61509fc840 PromQL: Promote negative offset and @ modifer to stable
Following the argument that breaking the invariant that PromQL does
not look ahead of the evaluation time implies a breaking change, we
still need to keep the feature flag around, but at least we can
communicate that the feature is considered stable, and that the
feature flags will be ignored from v3 on.

Write chunks via queue, predicting the refs (#10051)
* Write chunks via queue, predicting the refs

Our load tests have shown that there is a latency spike in the
remote write handler whenever the head chunks need to be written,
because chunkDiskMapper.WriteChunk() blocks until the chunks are written
to disk.

This adds a queue to the chunk disk mapper which makes the WriteChunk()
method non-blocking unless the queue is full. Reads can still be served
from the queue.

beorn7 4727c41a4b Update Go dependencies
Note that go.mod has been manually modified to use the following
versions:

- k8s.io/api v0.22.4
- k8s.io/apimachinery v0.22.4
- k8s.io/client-go v0.22.4

The current version of those modules requires Go1.17, which we only
intend to require once Go1.18 is out.

tsdb: use simpler map key to improve exemplar ingest performance (#10111)
* tsdb: fix exemplar benchmarks

Go benchmarks are expected to do an amount of work that varies with
the `b.N` parameter. Previously these benchmarks would report a result
like 0.01 ns/op, which is nonsense.

* tsdb: use simpler map key to improve exemplar perf

Prometheus holds an index of exemplars so it can discard the oldest one
for a series when a new one is added.
Since the keys are not for human eyes, we can use a simpler format
and save the effort of quoting label values.

* Exemplars: allocate index map with estimated size

This avoids Go having to re-size the map several times as it grows.
16 exemplars per series is a guess; if it is too low then the map will
be sparse, while if it is too high then the map will have to resize once
or twice.
