Currently, it's not explicitly called out which permissions are needed
for service discovery of EC2 instances. It's not super hard to figure
out, but it did involve a bit of guesswork when I did it yesterday, and
I figure it's worth saving people that effort.
I've also seen examples around the internet where people are granting
much broader permissions than they need to, so maybe we can save on that
by explicitly saying what's needed.

It's currently possible to use blackbox_exporter to probe MX records
themselves. However it's not possible to do an end-to-end test, like is
possible with SRV records. This makes it possible to use MX records as a
source of hostnames in the same way as SRV records.

This follow a simple function-based approach to access the count and
sum fields of a native Histogram. It might be more elegant to
implement “accessors” via the dot operator, as considered in the
brainstorming doc [1]. However, that would require the introduction of
a whole new concept in PromQL. For the PoC, we should be fine with the
function-based approch. Even the obvious inefficiencies (rate'ing a
whole histogram twice when we only want to rate each the count and the
sum once) could be optimized behind the scenes.
Note that the function-based approach elegantly solves the problem of
detecting counter resets in the sum of observations in the case of
negative observations. (Since the whole native Histogram is rate'd,
the counter reset is detected for the Histogram as a whole.)
We will decide later if an “accessor” approach is really needed. It
would change the example expression for average duration in
functions.md from
histogram_sum(rate(http_request_duration_seconds[10m]))
/
histogram_count(rate(http_request_duration_seconds[10m]))
to
rate(http_request_duration_seconds.sum[10m])
/
rate(http_request_duration_seconds.count[10m])

We always track total samples queried and add those to the standard set

We also allow optionally tracking per-step samples queried. This must be

The engine flag is exposed via a Prometheus feature flag, while the
query flag is set when stats=all.

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

feature flags will be ignored from v3 on.

Since `/api/v1/write` is a mutating endpoint, we should still activate
the remote-write-receiver explicitly. But we should do it in the same
way as the other mutating endpoints, i.e. via a flag
`--web.enable-remote-write-receiver`.
This commit marks the feature flag as deprecated, i.e. it still works
but logs a warning on startup. This enables users to seamlessly
migrate. With the next minor release, we can start ignoring the
feature flag (but still warn a user that is trying to use it).

* remote-write: slow down retries to avoid DDOS
Increase the default max retry time from 100ms to 5 seconds.
Remote write calls are retried after a recoverable error such as the
back-end returning 500. Prometheus waits the minimum time and retries,
then doubles the wait on each subsequent retry until the maximum is
reached.
If some data is still getting through, remote-write will also increase
shards, and the default maximum is 200. 200 shards sending every 100ms
is 20 calls per second, to a back-end that is already in trouble.
5 seconds was chosen to match the default BatchSendDeadline: if we can
afford to wait that long for no response, then we can wait the same time
to retry. We will reach 5 seconds after 9 successive failures.

* optimize Linode SD by polling for event changes during refresh
Most accounts are fairly "static", in the sense that they're not cycling
through instances constantly. So rather than do a full refresh every
interval and potentially make several behind-the-scenes paginated API
calls, this will now poll the `/account/events/` endpoint every minute
with a list of events that we care about. If a matching event is found,
we then do a full refresh.
