Allow Randomization of Archive Drive Destinations

Why not just use the index feature as is and specify a different number for each plotter? Though there is a change related to that in #855 based on discussion in #847. Also, in cases of "extreme" archiving needs you may be interested in https://github.com/rjsears/chia_plot_manager.

I must have missed the index feature, where was that?

Hidden somewhere in the code probably... yeah, our documentation needs work, sorry.

archiving:
  index: 0

Just set it to a different number on each plotter, counting up from 0. This doesn't cover all cases and might become fancier as you suggested by checking for rsync tmp files or other, but it does do a useful thing. When you get down to fewer drives than you have plotters then yeah, there's hazard of collisions.
