Periodic timer instead of number of requests

[lowlyocean]

Running Gitlab on a memory-constrained RPI2, where unicorn-worker-killer is used to restart workers after every X requests. Problem is that requests are infrequent and memory leaks accumulate while worker is running (even without any requests). Would be great to have option to set a time interval for the memory check instead of only doing it every X requests.

I tend to agree that number of requests alone seems like an arbitrary method of deciding when to restart.
