docs: Gets bindings for the whole hierarchy of children for a specified Element
  and filters out bindings which are not relevant (based on the parent model)
  
  @param {sap.ui.core.Control} oElement - Starting point of the search
  @param {sap.ui.model.Model} oParentDefaultModel - Model for filtering irrelevant binding paths
  @param {boolean} [bTemplate] - Whether we should consider provided element as a template
  @param {string} [sAggregationName] - if aggregation name is given then only for this aggregation bindings are returned, if not then all aggregations are considered
  @returns {Array} - returns array with all relevant bindings for all properties of the element
