[PATCH 1/2 v3] VMD: remove add from switch configuration
Remove configuration items on switches for:
* adding static interfaces
Adding static interfaces are to be set in hostname.if.
Changed rule on rdomain:
* vm->interface->rdomain takes precedence over sw->rdomain
Update examples/vm.conf and vm.conf manpage to reflect changes.
Comments? Ok?
