Evgeny Lazarev 970b1301b5 Cleanup IR v7 from the MO (#1008)
* Removed back phase transformations related to IRv7

* Fixed setting value for the input port using the 'set_value' method

* Removed front and middle phase transformations related to IRv7

* Cleanup the rest of the Model Optimizer transformations from IRv7 specific transformations

* Final cleanup of the deprecated IR v7 related code

* Removed 'blobs_as_input' usage in the Model Optimizer.

* Removed function '_fuse_add' from the Model Optimizer since it is not used anymore.

* Removed 'keep_in_IR' node attribute for FakeQuantize ops in the MO

* Disabled failing gpu_engine.user_context test
