Setter method for afts, mapped from YANG variable /network_instances/network_instance/afts (container)
    If this variable is read-only (config: false) in the
    source YANG file, then _set_afts is considered as a private
    method. Backends looking to populate this variable should
    do so via calling thisObj._set_afts() directly.

    YANG Description: The abstract forwarding tables (AFTs) that are associated
with the network instance. An AFT is instantiated per-protocol
running within the network-instance - such that one exists for
IPv4 Unicast, IPv6 Unicast, MPLS, L2 forwarding entries, etc.
A forwarding entry within the FIB has a set of next-hops,
which may be a reference to an entry within another table -
e.g., where a Layer 3 next-hop has an associated Layer 2
forwarding entry.
