Improvement: output request count

[ylecuyer]

Improve the output

• mark worker as killed / booting
• change order of optional fields
• add request count (this is based on Instrument requests count puma/puma#2106)

Looks nice! Thanks for the video. Two minor things:

• is the request number in red when it's big? For people who don't use worker killer it may look weird (always red)
• "Rqs" sounds a bit like requests/seconds to me, I would probably choose something like "Req" instead.
  Good job :)

Right, I'll remove the color

I discussed this with @misdoro and I had the same feeling, I'll change it to Req
