Use grid topology for bitfileds distribution messages (#5389)

Browse Source 
* Move NewGossipTopology -> SessionGridTopology outside as this implementation is shared

* Add method to return peers difference between topologies

* Implement basic grid topology usage for the bitfield distribution

* Fix tests

* Oops, fix tests

* Add some tests for random routing

* Add a unit test for topology distribution

* Store the current and the previous topology to match sessions boundaries

* Update tests

* Update node/network/bitfield-distribution/src/lib.rs

Co-authored-by: Andronik <write@reusable.software>

* Update node/network/protocol/src/grid_topology.rs

Co-authored-by: Andronik <write@reusable.software>

* Update node/network/bitfield-distribution/src/lib.rs

Co-authored-by: Andronik <write@reusable.software>

* Add some debug

* Fix tests as HashSet order is undefined
