Assignment

Any user can claim an issue via @rustbot claim. Users who can be directly assigned to the issue will be; users who can't will receive a "claimed" message in the top-level comment (and rustbot will be assigned). It is possible to override someone else's claim (no warning/error is given).

You can drop your claim to the issue via @rustbot release-assignment; Rust team members can do the same if they want to release someone else's assignment.

@rustbot assign @user can be used only by Rust team members and will assign that user to the issue (with same rules as before -- either directly or indirectly).
