eipp: add Allow-Temporary-Remove-of-Essentials
A rather special need option, but the internal planer supports this and
we have a testcase for it & sometimes it is hit (as a bug through). The
option itself mostly serves as a reminder for implementors that they
should be careful with removes and especially temporary removes if they
perform any.
