[Tacker][dev] Scaling and auto-healing functions for VNFFG

Hello tacker team and all,   I'm hochan lee and graduate student from korea univ.   Our team is interested in SFC and VNFFG, especially HA of VNFFG.   We are intereseted in scaling and auto-healing functions for VNFFG proposed in Tacker Pike Specifications. https://specs.openstack.org/openstack/tacker-specs/specs/pike/vnffg-scaling.... https://specs.openstack.org/openstack/tacker-specs/specs/pike/vnffg-autoheal...   We think these functions hadn't been developed yet. Are these features currently being developed?   If not, can we go on developing these features for contribution?   We wanna join next tacker weekly meeting and discuss them.   Thanks,
