Setter method for l1_spf_timer, mapped from YANG variable /isis_state/router_isis_config/l1_spf_timer (container)
    If this variable is read-only (config: false) in the
    source YANG file, then _set_l1_spf_timer is considered as a private
    method. Backends looking to populate this variable should
    do so via calling thisObj._set_l1_spf_timer() directly.
