> For 1-1 edge vertex configured event may be sent incorrectly

>
> For a fully configured 1-1 vertex configured event will be sent after init
> because the vertex manager does not signal intent to reconfigure. However a
> change in parallelism upstream on the 1-1 edge can cause this vertex's
> parallelism to be updated accordingly. This breaks the guarantee that
> configured should be sent after vertex is fully configured. This is because
> update of parallelism on 1-1 edge has until now been hard-coded in the Vertex
> code. This can be removed now with the InputReadyVertexManager handling the
> 1-1 edge and the addition of vertex state updates. Not only will this fix the
> issue but also remove the special handling for 1-1 edges in the AM which
> should not be there for cleanliness.
