Introduce an ignored subgraph

[andrey-churkin]

Changes

Introduce an ability to define subgraph in ignored scope

Reason for changes

The models get more complicated in terms of structure. Noticed many times, that it's impossible to exclude some parts of the model from quantization using the existing ignore scope functionality.
