Allow setting of Slicer State at report level - without having to find individual visual objects

Power BI Embedding allows for slicer state to be set when initial embedding is performed. An array of ISlicer objects can be passed into an IEmbedConfiguration - targeting slicers by table/column names.

After embedding has completed, the only way to update a slicers state is to use 'setSlicerState' on each individual visual. As described here: https://github.com/Microsoft/PowerBI-JavaScript/wiki/Slicers#set-slicer-state

This requires a developer to iterate through the report object hierarchy (Report -> Pages -> Visuals) iterating over the visuals to find the target slicer by ID or Name.

Both ID and Name are problematic at times (ID is random, and names have a habit of changing). The code to loop through the report hierarchy is also very verbose.

Idea/Suggestion:
Allow updates to visual slicers to be done at the report object level - using an array - matching the functionality of the initial configuration object allowing targeting by slicer binding (table/column).

e.g.

const mySlicers: pbi.models.ISlicer[] = buildSlicerObjects () ;
report.setSlicers(mySlicers);
