On stop command call Main.stop() runs
`remove_interface("*", pim=True, membership=True, ipv4=True, ipv6=True)`.
Therefore if a PIM interface was added for network interface eth0, the call
`remove_interface('eth0', True, True)` will evaluate the condition
`membership and not membership_interface` as True and the PIM interface will
never be removed.
Furthermore
`remove_interface("*", pim=True, membership=True, ipv4=True, ipv6=True)` will
do calls like `remove_interface('lo', True, True)` then calling
`remove_virtual_interface('lo')` and the line
`index = self.vif_name_to_index_dic.pop(interface_name, None)` will cause a
KeyError when running
`del self.vif_name_to_index_dic[self.vif_index_to_name_dic[index]]` or
`mif_index = self.vif_name_to_index_dic.pop(interface_name)`.
