Refacttoring of MenuSequence and related code for NewJO integration
The goal of the MR is to allow the same code (literally the same w/o if/else) to create CF and DF for new JO and existing JO. In the first commit MenuSequence attributes access were eliminated from other classes and replaced with method calls. Next step will be creation of MenuSequence subclass sharing all CF/DF wiring code with existing class but adding CA merges where necessary. Tagging @fpastore for preview
