Larger messages cost less, because the per-message overheads at sender
and receiver are spread over more samples.
Example: scraping 1.5 million series every 15 seconds will send 50
messages per second.
Previous default was 500.

* Introduce out-of-order TSDB support
This implementation is based on this design doc:
https://docs.google.com/document/d/1Kppm7qL9C-BJB1j6yb6-9ObG3AbdZnFUBYPNNWwDBYM/edit?usp=sharing
This commit adds support to accept out-of-order ("OOO") sample into the TSDB
up to a configurable time allowance. If OOO is enabled, overlapping querying
are automatically enabled.
Most of the additions have been borrowed from
https://github.com/grafana/mimir-prometheus/

- tracing: Always restart the tracing manager when TLS config is set to
reload certificates
- tracing: Always set TLS config, which could be used e.g. in case of
potential redirects.

* 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.

* 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.

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.
