spectrum_router and spectrum_mr have several APIs that are used to manipulate configurations originating from ipmr fib notifications. Following previous patches all the protocol-specifics that are necessary for the configuration are hidden within spectrum_mr. This allows us to clean the API and make sure that other than choosing the mr_table based on the fib notification family, spectrum_router wouldn't care about the source of the notification when passing it onward to spectrum_mr. This would later allow us to leverage the same code for fib notifications originating from ip6mr.
