Work with a 'running config' / live env

Currently you need to reload the entire system, restarting all peers, routing and create a routing convergence if peers depended on the route. I suggest two things:

1. signal the peer if this side goes down gracefully (and reconnect using different timers, for a fast reconnect).
2. create childs and have a main proces that runs, kicking of chils for each plugin. Leave the main process (router) and childs (peerings) running unless something has changed. If there is a change either just add a new peering (its bad to have to restart everything to add something live) or only restart the affected peering child plugin.

This would create a lot more stable connector as if i am looking now, with 8 peers on a node, it takes quite some time. Also each peer seems to be started and connected in a sync way, causing it to take more time ... i dont see why this could not be done async as each peering should not be depending on each other and just collect routes.
