    Dump Node Registration linked list

    Usage:
    dnr <addr of vlib_node_registration_t> [total] 
       - dumps all nodes in registration list with name and type. Gives total# node registrations.
    ie
    dnr vm->node_main->node_registrations
    Will print each nodes name and type from the node_registrations linked list with a 
    total at the bottom

    dnr vm->node_main->node_registrations total
    Only prints total

    *** WARNING: this is linked list traversal. Can take a couple of seconds to complete.
