Merge pull request #1472 from remibergsma/47_fix_static_router_master_change

Apply static routes on change to master stateRefactored static routes for private gateways so they also get loaded when the router switches to master state. Otherwise they're lost and connections drop after fail over.

* pr/1472:
  apply static routes on change to master state
