Revert random time.sleep in spawn_workers

[blueyed]

I came across the following code added in 3ade8e8:

gunicorn/gunicorn/arbiter.py

Line 617 in 933b210

time.sleep(0.1 * random.random())

This adds (random) overhead/slowdown during startup, and from skimming the comments in the issue it was meant for (#514) it is not confirmed to be helping really.

I suggest removing it for faster, more predictable startup.

(A related issue that might help with adding delay during startup: #514)

imo this 10 year changes is still useful as it ensure to not make the system too busy. I will close it for now, but if you have any production example where it can be useful, I am happy to revisit this isssue.
