KRACOEUS-7596:data override

here is my first go at data override some issues i am still working on.

1.)dictionaryAttribute and dictionaryObjectEntry don't seem to be working with experssions.  I have gotten them to work by adding the dataoverrideinputfield, which makes it work for the data override tab, however, the collection isn't rendering values correctly.

2.)once you create a data override and are directed to the send notification dialog, need to figure how to direct to the last step instead of the first.

3.)The KNS screen to add Prop Dev Data Override has issues. 
there should be a constant or enum for this
