gluon-l3roamd: init: dynamically configure mesh interfaces gracefully during reload 

This patch makes use of the new feature in l3roamd to gracefully
add, remove and list the mesh interfaces that are currently in use. This
helps when changing mesh interfaces often - a characteristic of the
wireguard protocol implementation as in the previous behavior all local
clients are dropped when adjusting mesh interfaces.
