Deprecate the multicastInterfaces option

[tnqn]

Some distros have exposed the multicastInterfaces option and made it
uncommented in the config file. antrea-agent would crash if a cluster
upgrades to v1.7.0 but doesn't remove the option. This patch adds the
option back and deprecates it in a compatible manner.
