This is supposed to lower the memory footprint of all Puma workers. The reports code will occupy needed memory in one Sidekiq worker instead of in several Puma processes. The current code doesn't limit the execution time yet. We either need a way to terminate the report rendering after a while or send an email with a link to access a rendered report.
