Reduce wait timings for Sidekiq jobsreduce-sidekiq-wait-timings

This reduces the time spent waiting for Sidekiq jobs to complete in
JobWaiter, and reduces the sleep interval when trying to acquire the
lease for refreshing authorizations. These changes should reduce the
time spent just waiting for a lock, which we seem to be spending most
time in when running the AuthorizedProjectsWorker.
