Refactor Sidekiq workers to reduce differences between CE and EE

See merge request gitlab-org/gitlab-ce!24466

Edits to issues CSV import docs

See merge request gitlab-org/gitlab-ce!24554

This change allows the GitLab rails and sidekiq components to receive
tracing spans from upstream services such as Workhorse and pass these
spans on to downstream services including Gitaly and Sidekiq.

This change will also emit traces for incoming and outgoing requests
using the propagated trace information. This will allow operators and
engineers to view traces across the Workhorse, GitLab Rails, Sidekiq and
Gitaly components.

Additional intra-service instrumentation will be added in future
changes.
