Bump Sidekiq 5.1.3 to 5.2.1
The most significant change in this version is that the default
concurrency has been lowered from 25 to 10 (https://github.com/mperham/sidekiq/issues/3892).
This doesn't affect omnibus-gitlab because the concurrency is controlled via a
setting that defaults to 25 anyway and is passed in via the -c
command-line
parameter.
However, source installations (including the GDK) will have to either specify the concurrency in
sidekiq.yml
or use the -c
option.
