Protocols have now assigned startup phases

Browse Source 
For now, there are 4 phases: Necessary (device), Connector (kernel, pipe), Generator (static, rpki) and Regular.
Started and reconfigured are from Necessary to Regular, shutdown backwards.

This way, kernel can flush routes before actually being shutdown.
