There might be another possibility for leakage. If the resource mangager
for the webhook resource crashes, OTP might log the spec for the
resource manager which contains the Config and thus the Authorization
header. This is probably an issue for other resources as well and should
be fixed in another commit. The following issue has been created for
that:

This reduces the log level from error to warning in places that are
connected to the influxdb bridge. Transient errors for external
resources should not render an error log.
This will inevitably fail: it's not generally possible to update
different keys through the same cluster connection, one or more
update will fail with `MOVED` status. This testcase should serve
as a regression test later.
some telemetry events from wolff are discarded:
* dropped:
this is double counted in wolff,
we now only subscribe to the dropped_queue_full event
* retried_failed:
it has different meanings in wolff,
in wolff, it means it's the 2nd (or onward) produce attempt
in EMQX, it means it's eventually failed after some retries
* retried_success
since we are going to handle the success counters in callbac
this having this reported from wolff will only make things
harder to understand
* failed
wolff never fails (unelss drop which is a different counter)
With this, we avoid performing work or replying to callers that are no
longer waiting on a result.
Also introduces two new counters:
- `dropped.expired` :: happens when a request expires before being
sent downstream
- `late_reply` :: when a response is receive from downstream, but the
caller is no longer for a reply because the request has expired, and
the caller might even have retried it.
A new atom was created every time one did a dry run of a Kafka bridge
(that is, clicking the Test button in the settings dialog for the
bridge).
After this fix, we will only create a new atom when a bridge with a new
name is created. This should be acceptable as bridges with new names are
created relatively rarely and it seems to be useful to have an unique
atom for every Wolff producer.
