so this is a new feature right.
this is not a bug fix so this also need a neutron feature freeze exception.

i have not reviewd the patch yet but didnt we agree to now allow modifyign existign rules in place
os i assume the replacemnt this enables is changign form one qos rule set to another.

looking at the neutorn patch this seams incomplte and only allows modifying the placment allocation i
a limited edgecase, mainly when teh prot was orginally booted with a qos policy.
as written i dont think https://review.opendev.org/#/c/747774/18 should be merged.
im reviewing it now.
