Added support for importing v1 flow events from json

Previously we didn't import flow events to the database.
Added FlowTracker - a data structure that helps to import flow events
Added additional logic to SliceTracker, now it interacts with
FlowTracker and notifies about any new slices via callback.
Flow Events version 1 are now importing to the database, table "flow",
support for version 2 would be added in the following CLs
