Delete an existing user
Pass reassignTo to hand the deleted user's contacts to another user; the reassignment then runs asynchronously. A reassignTo that is not a user ID, or that names the user being deleted, returns a 422, and one that names a user the account does not have returns a 404. This supersedes DELETE /users/{fromUserId}/reassign_contacts/{toUserId}.
