Setter method for track_interface, mapped from YANG variable /interfaces/interface/subinterfaces/subinterface/ipv4/addresses/address/vrrp/vrrp_group/interface_tracking/config/track_interface (leafref)
    If this variable is read-only (config: false) in the
    source YANG file, then _set_track_interface is considered as a private
    method. Backends looking to populate this variable should
    do so via calling thisObj._set_track_interface() directly.

    YANG Description: Sets an interface that should be
tracked for up/down events to dynamically change the
priority state of the VRRP group, and potentially
change the mastership if the tracked interface going
down lowers the priority sufficiently
