Allow moving to no iteration

[DanielNoord]

In our sprint workflow we'd like to move all "In progress" issues to the next iteration, but want to move all "Todo" issues to no iteration to show that we overplanned and need to actively put it in our sprint again.

Would it be possible to add none to the allowed fields in new-iteration as a way to unset the iteration field for a selection of issues?

This makes sense, I'll see when I have time to do it but a PR is also always welcome 😇

I might have time to dive into this, but don't think so.

One question upfront: from experience with the Github API, do you know if this is even possible? Do they allow POST/PUT with null?
