  - [baremetal] idf for opnfv_vm and update the pdf
    
    Physical hardware PODs provide a pdf and a idf to describe hardware and other
    information (e.g. what is the purpose for each interface). To reuse the
    same code for opnfv vm and also become consistent, we should also describe
    the opnfv vm with an idf and a pdf. This patch simplifies what needs to
    be done for baremetal, especially for this (future) patch:
    
    https://gerrit.opnfv.org/gerrit/#/c/60797/11
    
    As we add an idf, we should update dynamic_inventory and how we create
    the opnfv vm. Obviously, he opnfv_vm.yml gets removed.
