Implement VNFFG support for NS

This patch will add VNFFG support for NS. In NSD, users can
describe VNFDs and nested VNFFGDs inside. When NS is created,
VNFs and VNFFGs are also created too.

Work items of this patch:
1. Add sample nsd templates
2. Update NFVO plugin to adapt VNFFGD template extraction
    from NSD and create VNFFGs using that template
3. Modify Mistral workflow to create/delete VNFFGs using NSD

User guide, defref will be added in following patches.
