Maximum number of reassigns

[sobolevn]

When marge user creates a merge request and is assigned to merge it, infinite loop happens.

And there's no stopping mechanism. I suggest to add something like --max-reassigns option to stop it.

Or to check if future assignee and author is the same user. It might be easier.

I think your suggestion of marge-bot not unassigning itself just to re-assigning to itself is the right one, I'd be happy to accept a PR to that effect.

This is just a minor issue, because it shouldn't happen outside people testing their marge-bot setup, but I agree it would nonetheless good to fix.
