Moved default route removal to tap interface handling in general. By default that default route is bad, and we can add it if we want to.
By default client template doesn't do dhcp, as it most likely times out and even if it doesn't, it should be done as part of topology config so that we get tcpdumps from start of topology rather than after dhclient.
Removed dependence on openwrt starting from client - no dhcp anymore by default -> no need to wait.
Fixed Home4 and addressed few remaining bird -> router/ir changes.
