Sidekiq::Killer
Kills Sidekiq processes when the RSS is too high.
It checks the memory usage of sidekiq after each job, and if the memory usage is higher than specified, it will wait for the specified grace_time before quieting the sidekiq process. After the shutdown_wait time it will forcibly kill sidekiq using the signal specified in shutdown_signal.
