/**
 * @ingroup ov_transformation_common_api
 * @brief ProposalScales transformation helps to silently avoid reshape issues on the scale-input of Proposal layer.
 *
 * Expected sub-graph looks like:
 *      Parameter [batch, 3 or 4] -> Reshape [-1] -(in: 3)-> PriorBox
 *
 * PriorBox operation accepts 3 or 4 values as scales from specification standpoint
 * PriorBox uses first set (batch) of scale values to proceed in the plugins
 * According to this we explicitly take first batch of scales with StridedSlice operation
 *
 * Resulting sub-graph:
 *      Parameter [batch, 3 or 4] -> Reshape [-1] -> StridedSlice[0: 3 or 4] -(in: 3)-> PriorBox
