Allow Option to Explicitly Deny Access in PI Data Archive

Create a Deny option to PI tag security in PI Data Archive similar to what is in Windows and PI AF. This would make restricting access to certain tags easier for administrators.

    I purposely don't use the "Deny" feature in the PI Asset Framework so that I know that any permissions that I grant remain granted. I find it simpler to just not grant permissions in the first place if I don't want someone having access to something rather than grant them and take them away later.


    Once you start using "Deny" (a counter to "Allow"), then people start wanting a way to counter a "Deny", also to make things easier, and then you need to track the priority of different permission settings, and it's not so easy anymore.
