From time to time, network issues or service outages can cause slow or

blocked communication, which can be difficult to diagnose.
To help diagnose these problems, rbintegrations now logs the time taken

for all outbound communications with third-party services, escalating

the logs to warnings or critical errors if the service takes too long to

respond.
Errors encountered during this time are logged with the same trace ID

that the timing logs use.
Since the new logging functionality used for this does not exist in

Review Board 7.0.x or older, a backport of log_timed() is provided in

rbintegrations.util.compat.logs. This module is considered internal

and will go away when we can rely on the modern support.

All unit tests pass.
