Added dynamic tables for preceding and following flows

Following/Preceding tables contain all entries of flow events table
that directly or indirectly connected to the starting slice.


FOLLOWING_FLOW(start_slice_id) - all entries of flow events table that
have flow.slice_out=start_slice_id or there is a chain of slice_ids:
start_slice_id -> slice_id_1 -> ... slice_id_n -> flow.slice_in
and each pair of neighbour slices in this chain has a flow between them

PRECEDING_FLOW(start_slice_id) - the same as FOLLOWING_FLOW but in
opposite direction.

CONNECTED_FLOW(start_slice_id) - union if following and preceding tables
