* 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.

* Add a feature flag to enable the new manager
This PR creates a copy of the legacy manager and uses it by default.
It is a companion PR to #9349. With this PR, users can enable the new
discovery manager and provide us with any feedback / side effects that
the new behaviour might have.

We have been Puppet user for 10 years and we are users of
https://github.com/camptocamp/prometheus-puppetdb-sd
However, that file_sd implementation contains business logic and
assumptions around e.g. the modules which you are using.
This pull request adds a simple PuppetDB service discovery, which will
enable more use cases than the upstream sd.

This adds a new metric exposing per target scrape sample_limit value. Metrics are only exposed if extra-scrape-metrics feature flag is enabled.
scrape_sample_limit will make it easy to monitor and alert on targets getting close to configured sample_limit, which is important given than exceeding sample_limit results in the entire scrape results being rejected.

Add a new built-in metric `scrape_timeout_seconds` to allow monitoring
of the ratio of scrape duration to the scrape timeout. Hide behind a
feature flag to avoid additional cardinality by default.

* PromQL: Fix start and end keywords masking label and metric names
This commit fixes an issue with the "at modifier" that introduced two
new keywords: `start` and `end`. In grouping options and in metric
names, these keywords took precedence over metric or label names, so
that those metrics and labels could no longer be referenced.

* 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.
