Use the same logic for advertising routes in Router and Network 
router.Query() allows to query the routes with given router.Strategy.
It uses the same logic as was implemented in flushRoutes but the code
was never updated. This way we are consistent across both router and
network packages.

Remove Solicitation from the network 
Instead, when a new peer is discovered it is sent a sync message i.e. we
do the full sync when discovering peers

Removed debug logs. advertiseToNetwork() replaced watchTable(). 
Debug logs that were helpful when squashing bugs have been removed.

advertiseToNetwork replaced the watchTable which originally watched the
routing table entries. We now take a different approach to propagating
the local registry services into the network registry.

Redefeind interfaces; Added better modelled data strauctures 
Router interface has been redefined which fits better with what we are
looking for.

Routing table now offers a comprehensive set of information about its
entries which will make up for rich queries in the future

Query interface has been defined to enable current basic and more
advanced queries in the future.
