Sidekiq structured logs should include project path
Currently sidekiq's structured logs do not include project path information, although sometimes they do include project ids.
This makes it difficult to correlate sidekiq issues with issues in Gitaly, Rails, etc, since the operator needs to first lookup the project id and then specifically search the logs for that.
https://gitlab.com/gitlab-org/gitlab-ce/issues/52834 is a good example of how the connection between a sidekiq job and a gitaly performance problem is masked by this problem.
