When logging arguments from Sidekiq to JSON, restrict the size of `args`
to 10 KB (when converted to JSON). This is to avoid blowing up with
excessively large job payloads.
The Correlation ID is taken or generated from received X-Request-ID.
Then it is being passed to all executed services (sidekiq workers
or gitaly calls).
The Correlation ID is logged in all structured logs as `correlation_id`.
