Design review (second): Access control on entries specified in MODDN operation (ticket 47553)

[thierry bordaz]

Hello,

Thanks to all your feedbacks, they helped me a lot and raised a
    severe limitation in the original design.
    I updated the design following the aci syntax proposed during the
    discussion.
    On the implementation side, it is a bit more complex but less than I
    expected. I have not yet investigated the impact of ger operations.

I think a big work will be the test side as the ACI syntax provides
    many options.

Note: I kept for the moment the original design in 'alternative no1'.

regards
