Note that this bugfix release also includes the update of the
containerd/containerd dependency, with the only purpose of shutting up
security scanner spam. We usually do not decument dependency updates
in the CHANGELOG. In this case, it isn't even doing anything. I plan
to mention the update in the announcement mail.

Do not block when trying to write a batch to the queue. This can cause
appends to lock forever if the only thing reading from the queue needs
the mutex to write. Instead, if batchQueue is full pop the sample that
was just added from the partial batch and return false. The code doing
the appending already handles retries with backoff.

If a queue is stopped and one of its shards happens to hit the
batch_send_deadline at the same time a deadlock can occur where stop
holds the mutex and will not release it until the send is finished, but
the send needs the mutex to retrieve the most recent batch. This is
fixed by using a second mutex just for writing.
In addition, the test I wrote exposed a case where during shutdown a
batch could be sent twice due to concurrent calls to queue.Batch() and
queue.FlushAndShutdown(). Protect these with a mutex as well.

When using Kubernetes service discovery on a Prometheus instance that's
not running inside Kubernetes, the creation of the service discovery
fails with a "no such file or directory" error as the special
`/var/run/secrets/kubernetes.io/serviceaccount/namespace` file is not
there. This commit moves the code that reads this file into the
if-branch where no `APIServer.URL` is given (that one basically makes
Prometheus assume it is running inside of a Kubernetes cluster).

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.
Signed-off-by: beorn7 <beorn@grafana.com>
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
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.
